Algodoo

A gun with expanding bullets that uses a laser to fire the bullets.
If you do as the scene says, you should get all the information about it that you need. I suggest using the red bullet, cause the green bullet is for destroying soft objects completely, and the red bullet is for destroying anything else.

If you have any idea how bullets work (and algodoo), you should be able to figure out why the green bullet is better for soft targets (as long as you do as the scene says).

Have fun, and please tell me how you like my bullets. I think I'm the first to ever make a bullet like this, but I'm not sure, so tell me if you can.
