Algodoo

A knife that can shoot its blade out of the handle. It was supposed to be like the real life ballistic knife, but it didn't turn out exactly as I'd hoped.

How to Use:

Drag a knife blade into the handle and pull it down untill it locks in.
Aim the knife at whatever you want to shoot.
Drag the button on the side in untill the blade fires off.

Please tap F11 or Tilde (~) and type Sim.Frequency = 500 to make the simulation run at 500Hz. If the simulation isn't running at 500Hz, then the blade won't stay in the handle, and instead will just launch off as soon as you let go of it, due to the immense spring power.
