Grape Shooter
Fri, Oct 7, 2011
Materials: Bean shooter (balloon, toilet paper tube or pvc pipe, tape), grapes or marshmallows, safety goggles
Activity: Attach an un-inflated balloon on a pvc pipe. Drop a grape down the tube, into the balloon. Pull and release the balloon to launch the grape. The safest pvc pipe for us was 16 inches long with a 1.5 inch diameter.
Research Questions: How does the angle of the shooter affect the path of the grape? How does the distance you pull the grape back, before shooting it, affect the grape's path? How does your method of shooting affect how much the grape becomes smashed?
