To build an Xpult catapult, you'll need a few basic supplies: a sturdy base (like a piece of wood or cardboard), a flexible arm (such as a wooden dowel or a plastic spoon), a pivot point (like a screw or a nail), rubber bands for tension, and a small projectile (like a marble or a ball). Additionally, you may want to use glue or tape for assembly and decorations, as well as a measuring tool for precision. Safety goggles are also recommended during testing.

An Xpult catapult works by storing potential energy in its elastic material (such as a rubber band) when it is pulled back or wound up. When released, this potential energy is rapidly converted into kinetic energy, causing the arm to swing forward and launch the projectile. The design of the Xpult allows for adjusting the launch angle and distance by changing the amount of tension on the elastic material.
The type of ball that can be launched farther with an XPULT catapult generally depends on its weight, size, and material. Lighter balls, such as a tennis ball or a small plastic ball, are typically launched farther because they require less force to achieve higher velocities. However, the aerodynamics of the ball also play a significant role; a well-designed, lightweight ball with a smooth surface can maximize distance. Ultimately, testing different types of balls is essential to determine the optimal choice for maximum launch distance.
