Code	/ PLEASE READ THE INSTRUCTIONS AND TRY IT! IT'S FASCINATING! This is a real phenomenon, I've done it myself. This simulation replicates exactly what I see when I do this expiriment. IF IT STOPS WORKING, JUST PRESS RESTART BELOW THE PROGRAM. 1. Turn on the sink water; it needs to be a very thin stream. 2. Take a DRY comb and run it through your DRY hair several times. 3. Don't touch anything, then hold the comb next to the stream of water. 4. The water will bend towards the comb, even up to a few inches! 5. Please let me know how it works for you in the tips and thanks! P.S. If you want, make a spin-off and show me what it looked like for you! @Jett_Burns / angleMode = "radians"; frameRate(60); // This is the strength of gravity.
