This is Ganesh and my fling machine. It blew the cotton ball into two bits, and the farthest bit went 35 inches. It is a pipe cleaner run through a straw, and bent at the ends. There was some foil at the end before. Earlier models could fling the cotton farther, but the materials were weak so the slingshot fell apart.
If I could alter the design, I would first use something other than the pipe cleaner to provide support for the rubber band, because the pipe cleaner bent a lot. If i could, i would just use solid poles and attach them to the desk and forego the straw as a whole. I should also learn how to actually use a slingshot. :D Our team is impeccable, so no change there. I feel other teams sufficiently solved the problem.
