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.

simplicity + accuracy + creativity = spectacular demonstration.

at times, it looks like DNA spinning around

The equation looks like this; T=2π√(L/g) where g=9.8 (approximate acceleration due to gravity on earth in metres/second^2) "L" being the length of the pendulum string, "T" being the period of 1 oscillation. if the pendulum string is shorter, the time taken to swing from one side to the other and will be shorter, this can explain the different time the swinging actions take, giving the wave like effect. Mass, height and shape are not important as air resistance is negligible in this scale of experiment guys.

I have nothing better to do than watch this over and over yay

Great video! I saved as a favorite to show to my six grandchildren. They're going to love it!
-
Awesome! My physics professor showed my class this during a lecture, and I loved it!
-
That's a real good explanation of the time period of a pendulum being independent of the bob mass and only depends on the length of the string!

Thx for this. It explains a lot of things. :) “If you want to find the secrets of the universe, think in terms of energy, frequency and vibration.” ― Nikola Tesla

I'm really trying hard to figure out why 250+ people gave this a thumb down
-
this is the coolest thing my eyes have ever been bestowed upon when i saw this and really noticed all the patterns i was amazed this is truly amazingly beautiful keep up the good work man and make some more stuff like this!
-
Wow I have never seen anything like this on my 91 years on earth. Amazing
-
I could watch this for hours..
-
This is just NUTS!
-
of all of your videos this one I have found to be the most thought provoking, there is just so much going on ...
