I don't watch America's Got Talent but I found this guy, The Kinetic King, by watching clips of the show. Some of you probably already know who he is and what he does. Still, his work is pretty incredible so if you do, then sit back and enjoy the show.
Kinetic energy is the energy of motion. Tim Fort, a.k.a. The Kinetic King, takes everyday objects and starts a chain reaction using kinetic energy (hence the title). Basically it's glorified dominoes (or dominoes on Steroids, as I like to affectionately call it). If you like dominoes you'll love this. He uses dominos, but he also uses cups, Christmas beads, balloons, wooden blocks, popsicle sticks, and more things that I can't remember or can't name. He does some neat stuff. Enjoy!
This last video is pretty neat. If you only watch one, watch this one!
