Algodoo

A modern version of the ancient chinese Fire Dragon. Well, almost, it's a rocket that shoots off arrows in the air, so it's pretty close.

Instructions:

On Scene Start:

1. Set at desired angle (30 - 45 degrees is good)
2. Hold Enter/Return until the rocket fires or press on the black lever at the back
3. Once fired, drag the latch downwards to open the breech, and pull out spent casing
4. Insert new rocket
5. Close breech

Repeat steps 1-5 until satisfied

Unlike the real thing, you can stand right behind this fire dragon as it's launching, because it launches like a spring bullet and then starts the rocket.

Can launch arrows up to 300 meters.

P.S.: I'm going by what I saw on mythbusters, so sorry if I get some stuff wrong.
