Be sure to watch the entire video to see all of the patterns that are created. At the end of the video there are 2 links to watch 2 more versions of the video.

This is a very well known effect that has been performed a countless number of times. I wanted to try and different version by using the black lights and also to add a little production value instead of just simply showing the effect.

The effect works by using a formula that provides the specific length for each string. When all of the pendulums are started at once the patterns will start to form. The pattern resets after about 1 minute. I glued white poster board on the sides of the nuts and used a black light, causing the white to glow.

You can download this song on itunes:

Name of song “Break Emotion”

Оо! В темноте-то ещё более эффектно смотрится этот старинный фокус-мокус.

wow it looks like DnA at some points

i love that

Lionel Obino says:

The entire motion like behavior is an illusion. A precise mathematical model of the phenomenon can be Obtained by solving for a dynamical system of 12 Differential equations one for each pendulum. Variation of the pendulum length leads to the discrepancy in the period. By Solving for the position of each pendulum (select an appropriate coordinate to project the position) at an arbitrary time t > 0 , you will get a beautiful description of the motion. Have fun.


omg thats really awesome nice job

fucking kill yorself you nignog

That's pretty neat can you make an instruct able for the leds you used I have an idea to build on this. Not as a pendulum though.

Jordan Munroe says:

The frequency of a pendulum is inversely proportional to its length. The rest is just resonance. Cool effect though. 🙂
