The Fascinating Mechanics of String Spin Tops
String spin tops are captivating toys that have entertained people for centuries. These simple yet ingenious devices operate on basic principles of physics, creating a mesmerizing display of motion and balance. But how exactly do string spin tops work?
At its core, a string spin top consists of a body (usually cone or disc-shaped) with a point at the bottom and a stem at the top. A string is wound around the stem, and when pulled quickly, it causes the top to spin rapidly. The spinning motion creates a gyroscopic effect, allowing the top to maintain its balance and rotate on its axis for an extended period.
The Science Behind the Spin
The physics behind string spin tops involves several key concepts:
- Angular momentum: As the top spins, it gains angular momentum, which resists changes to its rotation.
- Precession: The slight wobble observed in spinning tops is due to precession, caused by the gravitational force acting on the top’s center of mass.
- Friction: The interaction between the top’s point and the surface it spins on creates friction, which gradually slows the top down.
Understanding these principles can help enthusiasts improve their spinning technique and appreciate the intricate balance of forces at play.
Exploring the Diverse World of String Spin Tops
String spin tops come in a wide variety of shapes, sizes, and materials. Each type offers a unique spinning experience and aesthetic appeal. Here are some popular categories of string spin tops:
- Traditional wooden tops: These classic tops are often handcrafted and prized for their natural beauty and tactile feel.
- Metal tops: Known for their durability and long spin times, metal tops are favored by many enthusiasts.
- Plastic tops: Lightweight and affordable, plastic tops are great for beginners and casual play.
- Artistic tops: Some tops feature intricate designs or patterns that create stunning visual effects when spinning.
- Competitive tops: Specially designed for maximum spin time and precision, these tops are used in spinning competitions.
Each type of top has its own characteristics and appeal. Collectors often enjoy acquiring a variety of tops to experience the different spinning qualities and visual effects they offer.

6 simple knots you might need
Survival
28 May
These universal options will surely help you out more than once in a variety of life situations.
Iya Zorina
Author of Lifehacker, athlete, CCM
Having mastered a few simple knots, you can fasten even very heavy objects with just one rope, and if necessary, quickly release them.
We’ll show you five ways to securely tie things in transit, make an adjustable loop to hook onto a pole, and make a very strong knot that’s perfect for towing a car on a cable.
1. Arbor knot
For its simplicity and strength, this knot is also called the bowline, or “king of knots”.
With it, you can make a non-tightening loop at the end of the rope, fix it in rings or eyelets, wrap it around a support – a tree or a pole. After removing the load, the gazebo is easy to dissolve.
1. Make a small peg – loop to further tighten the knot. Keep in mind that it is not the main loop, so you do not need to make it big.

2. Pass the running end through the peg, passing it from below.
Frame: Interparus Yachting / YouTube
3. Wrap the running end around the main end.
Shot: Interparus Yachting / YouTube
4. Pass the running end into the peg so that it is parallel to the end of the rope already there.
Frame: Interparus Yachting / YouTube
5. Tighten the knot well.

2. Triple bayonet
This knot was used in maritime affairs. With it, you can tie the mooring ends of the ship to the mooring fixtures or secure heavy loads. It is really strong and suitable for strong pulling, but is easily untied when needed.
1. Throw the rope over the support, pass the running end behind the main end, and then insert it inside the loop and tighten.
Frame: Moscow RopeAccess / YouTube
You will end up with a knot called a half bayonet.
Frame: Moscow RopeAccess / YouTube
2. Follow the same steps again: pass the running end under the root, insert inside the loops and tighten.
Frame: Moscow RopeAccess / YouTube
It is important here that the half-bayonet is exactly the same as the first one. If you pass the running end not under the root, but above it, you get a cow knot, not a bayonet.
3. Perform the steps a third time. You will get a triple bayonet, which is considered the most reliable knot.

Note that all three nodes are the same.
3. Long Midshipman’s Knot
If you want to tie something, but still be able to adjust the length of the rope later, try this knot. It allows you to easily change the size of the loop, but when it is tightened, it holds tightly.
1. Make a loop, wrap the running end around the root from above and slide it through the loop.
Frame: Trailguide Pictures / YouTube
2. Wrap the running end around the root one more time.
Frame: Trailguide Pictures / YouTube
3. Repeat the same a third time with one more turn.
Frame: Trailguide Pictures / YouTube
4. Wrap the running end around the main end above the entire winding, and then slide it inside the resulting loop and tighten.
Frame: Trailguide Pictures / YouTube
5. If you did everything right, the knot will easily walk along the rope, and under load it will tighten on its own.

4. Looped Figure 8
This knot is useful for those who want to make a secure loop to attach a carabiner to. It is easy to tie, it can withstand heavy loads, and if necessary, it is quite easy to untie.
1. Fold the rope in half.

2. Make a loop of double rope by placing it on your finger.
Frame: VPSK Bogatyr Novosibirsk / YouTube
3. Make a peg by bringing the end with a loop on top.

4. Wrap the end with a loop around the other double end.
Frame: VPSK Bogatyr Novosibirsk / YouTube
5. Insert the end with the loop into the peg that is on your finger.

6. Tighten the knot.
Frame: VPSK Bogatyr Novosibirsk / YouTube
The double eight is ready.
5. Figure of eight with one end
This knot is a bit like the previous one, but it is a bit more complicated. But with its help, you can tie a rope to some static object and do it without using a carabiner.
Before hooking the rope to the support, you need to make a blank on it – a simple figure of eight.
Make a peg and the end that went on top, loop around the other end and stick it from outside to inside. Tighten. You will get a knot with two hemispheres.
1. Attach the rope to the support.
Shot: Change of mountain / YouTube
2. Insert the running end into the upper hemisphere of the knot from the inside out.
Shot: Change of mountain / YouTube
3. Slide the running end under the root and shove it into the lower hemisphere of the knot from the outside to the inside.
Shot: Change mountain / YouTube
4. Now you will need to shove the running end into the left side of the upper hemisphere of the node from the outside in, and then pull it out of the lower hemisphere. In the picture below, the required holes are marked in red.

5. Insert the running end of the rope, pull it out of the bottom of the knot and tighten.

6. The figure eight is ready.
6. Driver’s knot
Using this knot, you can secure a thing well with just one rope, without additional devices. Drivers often use it to secure cargo in the body or on a trailer.
1. Hook one end of the rope and roll up the peg. With your right hand, hold the junction, and with your left, move the loop down, passing it under the rope.
Frame: Stef Roberts / YouTube
2. With your right hand, turn the loop over and insert the end that is in your left hand into the hole.
Frame: Stef Roberts / YouTube
3. Tighten the knot.

4. Secure the rope on the second side, and then insert the running end into the loop.
Frame: Stef Roberts / YouTube
5. Tighten the rope well.
Shot: Stef Roberts / YouTube
6. Holding the knot with your left hand, drag the running end under the other ropes with your right hand.
Shot: Stef Roberts / YouTube
7. Insert the running end into the loop and tighten, then pull it under the ropes again.
Shot: Stef Roberts / YouTube
8. Insert the running end into the loop again and tighten.

Top rope
Today we will start a series of technical articles about mountaineering. We plan to cover both the very basics of mountaineering, describing in detail the techniques, nuances of technique and application, as well as more complex topics that are of interest to already experienced climbers.
Today we’ll talk about what, as a rule, any person’s acquaintance with a rope begins with – from the top rope.
Insurance can be: gymnastic, upper, lower and mass.
Gymnastic belay – belay with hands, without rope – used when climbing low rocky routes (bouldering) and in the initial sections of climbing with a lower belay.
Top insurance is used in climbing and when belaying a non-leader (2nd – 3rd participant) on a climbing route. With the top belay, the rope from the climber goes up, while the insurer can be both above and below the climber.
The bottom belay is used for belaying the leader in climbing and mountaineering. The rope goes down from the leader, and passes through guy wires fixed to the relief.
Mass (railway insurance) is used when it is necessary to ensure safety on difficult terrain for a large number of people, or when it is necessary to travel with a very heavy backpack.
Equipment.
Top belay is performed using a single or double dynamic rope and a belay device (hereinafter – SU). For mountaineering, it is recommended to use ATC type belay devices (reverso, basket, Shticht washer and similar) or a UIAA knot. In rock climbing, belay devices with increased friction (not automatic) of the Gri-Gri type and devices similar in principle of operation have become widespread.
Rope attachment.
The recommended method of attaching a climber to a rope is tying to a rope (figure eight knot or double bowline).
It is also possible to fasten the rope to the power loop of the fall arrest system using two coupled carabiners. This method is especially often used on climbing walls, and is applicable only for top insurance.
Snapping a carabiner through two loops of the safety system, parallel to the power ring, as well as snapping it into one carabiner – DANGEROUS!!! With this fastening, the load during the breakdown can fall on the latch of the carabiner. The latch, depending on the design and direction of application of the force, can withstand from 100 to 700 kgf (1-7 kN), which is less than the possible pull force.
The belayer attaches the belay device to the power loop of the belay system using a coupled carabiner. The wedge-shaped slots and/or teeth on the belay device must point down, the free end of the belay rope passes through the wedge-shaped slots in the DR.
When using a UIAA knot as a SU, use a pear-shaped socketed carabiner marked HMS or the letter H in a circle. It is important to control the position of the free end of the rope – it should not come into contact with the sleeve and / or the latch of the carabiner. Rubbing the rope against the sleeve can cause it to unlock, opening the latch of the carabiner and losing the belay.
If the belayer is higher than the climber, then it is convenient to use the control system of the ATC type in the guide mode (auto-blocking). In this mode, the ATC is a device of increased friction (similar to Gri-gri) and the load on the insurer during the jerk is significantly reduced. However, a PBX in auto-lock mode is not an automatic device. If you need to release the rope, the device must be blocked with a Munter-Mule knot.
The device is attached to the belay station and the rope is threaded into it, as shown in the photo. The landing gear and the rope in the landing gear are fastened with the help of coupled carabiners.
Preparation of the rope and place for the belayer.
The safety rope must be pulled over and laid in front of and slightly to the side of the belayer so that he does not step on the rope when moving while belaying. The end of the rope going to the climber should come out from above.
A knot is tied one meter from the end of the rope to prevent loss of the belay if the rope is too short. The recommended knot is half a grapevine knot.
The rope can also be tied to a belayer’s harness or station.
The area for the rope and belayer should be as level as possible – without large stones, bushes, etc. During the belay, the belayer must be able to move around for better control and visibility of the climber.
If the ground for the belayer is not level and/or dangerous, it is possible for the belayer to fall, and also if the weight of the climber greatly exceeds the weight of the belayer, then a self-belay is organized for the belayer, which should prevent him from falling or pulling him up during a jerk.
Control and mutual control.
Before climbing, the climber and belayer check the correct organization of the entire safety chain. The check is given according to the following scheme – ABCDE. Where A is anchor, station. B – backle, buckles on the safety system. C – carabiners, D – device, devices, E – end of rope, end of the rope (you can come up with your own memorization scheme – the result is important).
It is important to check the entire safety chain – incl. a safety system, knots, carabiners and SU from a partner. Mutual control avoids many mistakes and dangerous situations.
Communication .
When climbing, proper communication is the basis of safety. Commands are given loudly in the direction of the one to whom it is addressed. A common mistake is that commands are given quietly and in the wrong direction.
If the command is heard, then the command “Understood!” is given in response. If not heard or heard partially, then the command “I did not understand. Repeat”.
Before climbing, especially with a new partner, it is essential to discuss the commands used and their meaning.
It is important that all commands are heard and understood unambiguously! Loss of communication and errors in communication often lead to accidents.
If there is a direct line of sight between the climber and the belayer, commands can be duplicated using gestures, the meaning of which should also be agreed in advance.
The following commands are used.
- Insurance is ready.
- Issue.
- Choose.
- Fasten.
- Stall.
- Lanyard.
- Down. On a rope.
- Climbing down.
- Got it.
- I don’t understand. Repeat.
And others.
Before climbing, the climber must ask the question “Is the belay ready?” And does not start moving until the answer “Insurance is ready!”
Belay technique.
The belayer carries out insurance in shoes. Belaying barefoot or in half-removed rock slippers is dangerous!
The stance and position of the legs must be chosen in such a way that a possible jerk does not lead to a fall or impact on the terrain. Normal stance – facing the rock with one foot in front. The hand holding the rope should be as far away from the rock as possible – this will prevent it from hitting the terrain during the dash and possible loss of insurance.
When the climber moves up, the belayer chooses a slack on the rope so that it is slightly taut, but does not pull the climber and does not prevent him from moving.
The most common top belay mistake is the incorrect technique of interception of hands on the rope, when the belayer clamps in one hand the weight and free end of the rope above the belay device.
In this position, the effectiveness of the belay device is reduced by almost 10 times and the friction becomes insufficient to hold the fall. In practice, the belayer tries to hold the fall with one hand simply through the carabiner – because. the belay device in this position does not work.
For correct and safe belaying, the belayer intercepts the rope only below the belay device, constantly controls the rope below the device with at least one hand. In this position, the rope is correctly bent over the fall and there is enough friction to hold the fall.
Correct interception technique:
youtube.com/embed/hlP8dkyW_kw” frameborder=”0″ allowfullscreen=””/>
Don’t try to make very long turns on the rope – it’s better to do 2-3 short and fast moves than one very long one. With long interceptions, the rope is selected more slowly and more tangled.
If the belayer does not have time to choose the rope at the speed of the climber, he must inform him about this, and he must correct the speed.
At the command “Lock” – the belayer pulls the rope and holds it. If the rope needs to be held for a long time, the spotter blocks the SU with the help of the Munter-Mul knot (for more details, see the next article).
The descent can be organized by “parachute” on a rope and climbing.
When descending on a rope, the belayer etchs the rope in his hand or touches it with both hands. The speed of descent is not more than 1 meter per second. You need to be especially careful when climbing cornices, ledges and when landing.
When descending by climbing, the belayer gives out a rope with a slight slack so as not to interfere with the climber’s movement.
The organization of the descent when belaying the ATC type control system in the auto-lock mode is quite complicated and is described in a separate material
Forces and loads.
During a fall with top belay and in the absence of errors in the work of the belayer, the climber almost immediately hangs on the rope – there is usually no significant movement down and a jerk. But even with the ideal work of the insurer, the load on the breakaway will exceed 2.5-3 of his weight. The jerk on the insurer will be twice the weight of the one who has broken, and the load on the upper point, where the forces are added, will reach five times the weight of the one who has broken. In the case of even minor errors in insurance, these figures can grow by TWO-THREE times. In this case, the load on the upper point can reach one or more tons, and the insurer can be pulled with a force of 400 kgf. (4 kN)
Being aware of the possible effort in the system is necessary to assess risks, consciously use the correct belay technique, and manage those risks.
