Trick with treats, for Halloween this year I decided not to hand out candy. Instead I decided to launch candy at high speed at kids. This plan came about merely 2 days before Halloween and was executed with materials scavenger from the bone yard at LVL1 Hackerspace
. It was a lot of fun and I am happy with how it turned out but with such a short time frame and the hack job it is I had to leave out and things I will do another way next time. I will try to cover all of them in this instructable.
The propulsion system inside of the pumpkin is two fans that have had their blades replaced with fabric disk. The candy is funneled into the spinning disk then shot out of the mouth. It works the same way tennis ball or baseball launchers work.
