my physic project :D
me and my group had to do a physics project on potential elastic energy, so we made a giant pumpkin sling shot. it has two 8 foot long bungee chords at each corner of the net on a 7 and 1/2 foot high base. when the bungees are pulled back as far as we can get them w/ a hand winch and it is sitting on top of a picnic table we can launch stuff about the length of a football field.
the kid in the picture is not me, just a goofy kid in my group.
I drive a station wagon.
