Precision Shooting

Crash and Bowser will have to be on target in this challenge. Their vehicles will have to be able to shoot mylar balloons out of the sky as they drive around a dirt road course. They will have 5 minutes to shoot as many balloons down as they can with whatever devices they build. The team with the most balloons popped in either of two runs wins the challenge. Ready...Aim...Fire!

Crash thinks a giant crossbow, air cannon and disc-flinger will do the job. The cross-bow will require car springs which are easy to find but this design hasn't worked before. The air cannon will require good pipe for a barrel and some special valves for releasing the air. It will also need some sort of compressor to store the air. The disc flinger is sort of complicated but is, in essence, a baseball pitching machine that shoots a steel frisbee.

Bowser also wants an air cannon, which means he'll have to fight Crash for valves, pipe and a compressor. Bowser will be making his own air storage system which will take time to build. He is also going to make a spring loaded catapult. Two I-beams will ping a trolley forward with garage door springs. It's not exactly complicated but time consuming. Will two systems be enough?

very well so it gets the shop
