Test Firing a Small Catapult, and Tips on how to improve performance
A lot of people ask how far a catapult will fire a projectile. In this video I show you exactly how far I get my torsion catapult to fire, using a tape measure. The distance from the catapult to the wall is seventeen feet. And I show several different techniques for getting it to fire even further.
A quick overview of the tips that you use to get better performance:
Wind the string or rope tighter
Put a piece of wood across the base of the catapult to keep it strong, so you can wind even tighter
Lengthen the swing arm of the catapult or move the cup up or down the length to different spots
Move the crossbar up or down, or add pieces of wood to it to change the trajectory angle
