Here are the results:
The idea for this pendulum art came from a website with photos taken by Scott A. Ensminger.
On his site he describes a more sophisticated process than my own (hanging a small flashlight and thread from a tack on the ceiling) for created these images - and he also has some more intricate photos!
The bottom-right picture for today was created by hanging the pendulum from a decelerating ceiling fan. The other "ceiling fan photos" didn't turn out as well as the simple pendulum pics - maybe room for a little more experimentation here.
If you have a camera that allows a long exposure time (these were 25 seconds each), give it a try! Every initial swing of the pendulum will give a new pattern.
It reminds me of that old school Spirogram toy I once had.
ReplyDeleteSo awesome!
A gorgeous illustration of the principles of physics. Well done!
ReplyDeleteThose pics are really neat! What fun! Oooooohhhhh....I just had an idea.....I will send you an e-mail.... :)
