The Physics of "Punkin Chunkin" (2012x177)

Date de diffusion: Nov 20, 2012

"Punkin Chunkin" is the United State's annual contest to see whose homemade machine can hurl a pumpkin the farthest (without explosives!). Every November, thousands of amateur engineers converge on a farm in Delaware to put their contraptions to the test. The machines at the Punkin Chunkin festival rely on physics to get the pumpkin airborne & Hank is here to give you all the fascinating details of how it works. Happy Thanksgiving! Thanks to Science Channel for helping with this episode and giving us some money and footage to produce it.
