Descrizione
This rubber band powered mini catapult is only about 10cm long, but it packs a punch! I used a super-strong rubber band that allowed me to launch items up to 1.5 cubic centimeters about ten feet across the room. The catapult's power is dependent on the strength of your rubber band and how far you pull it back.
