Jumping Spider-Type Mechanism

Overview
The Jumping Spider-Type Mechanism functions using springs that are pulled back. There is a gear that has a side with teeth and a side without when the gear spins and reaches the side without teeth, the springs are released and the prop "jumps" upwards and towards you. The motor then spins the gear again and as the teeth reach the mechanism again, the prop retracts back into the down position.

Jump Strength and the Down Position
It is recommended that when you store a prop with this mechanism, you keep the mechanism in the up position. Leaving a prop with a Jumping Spider-Type Mechanism in the down position for very long periods of time causes strain on the springs, this strain on the springs ends up bending them, which will cause the prop to jump weaker.
