This is a slingshot that shoots a missile (non-explosive, but it has 100 density!!!) EXTREMELY far. TONS of power! MEGA range!

f to fire.

How it works is a missile is attached to a ball using a tight spring. The ball is attached to a post using a tight spring. When I release it, the ball and the missile get rocketed forward. A killer box then kills the square, 'cutting' the spring! So it releases the missile into the sky.
