Magnepult

Our catapult will use an electromagnet to get the repulsive force and launch the water balloons.

Catapult-Magnepult

This is my groups catapult. We intend on using an electromagnet to propel the arm holding the water balloon.

Vertical bar- MUGS

The fact that we put the vertical bars 2/3rds of the way down the base allows it to ideally distribute the weight and forces of the catapult.

Catapult lever arm

Projectile dysfunction

This is the lever arm of our catapult that launches our water balloon through the tension in bungee cords. It is made of PVC pipe and an insulator (to prevent the wood from bruising and breaking) and requires a decent amount if torque to operate
