We were required to create a device that will toss a grape accurately within a given range
-The range will be between 5 and 15 feet
-Must fit in a square foot footprint in collapsed form
-It must be made out of found materials
-It cannot use pressurized gases

Procedure
We drew our design on inventor

Materials

Wood

Summary

It took us a while to get the power up to be able to throw the grapes 15 feet. After adding many rubber bands, we got it to fire the highest required range.
