The Rocket Trike

The SPS Rocket Trike is an adult tricycle powered by a carbon dioxide fire extinguisher. The Rocket Trike illustrates Newton's Third Law commonly known as the Law of Action and Reaction. The rocket trike exerts an action force on the escaping carbon dioxide gas. The gas in turn exerts a reaction force on the rocket trike causing it to accelerate. What a blast!
