Eisco® DIY Miniature Catapult

Miniature catapult for demonstrating STEM concepts with a medieval weapon.

Catapults were one of the most influential elements of siege warfare over the last 2500 years. The easy to build design allows students, teachers, or science lovers to play with the physics of catapults. The small size makes the catapult excellent for individual building, and makes an interesting desktop or side table piece. Educational topics this kit can be used to demonstrate includes force, acceleration, center-of-mass, vector components, Hooke’s law, parabolic trajectories, and class 2 levers.

Kit includes catapult base, catapult left and right sides (symmetric except for counter-sinks), catapult lever arm, 8 rubber bands, 4 wood screws, 3 dowels, 1 c-shaped screw hook, 1 ping pong ball, cardboard storage box, and instructions for assembly and experimental activities. (A medium size Phillips screwdriver is required but not included). Catalpult is approximately 3.5" long when assembled.
