Fire Extinguisher Rocket Cart
Purpose:To illustrate conservation of momentum as applied to rocket thrust.
Procedure:Don the safety helmet! Place the extinguisher in the holder on the cart. Sit on the cart facing the extinguisher and point the extinguisher away from you. Check to make sure you have a clear path. Pull the safety ring from the handle of the extinguisher and blast off (squeeze the handle).
Hints:This demo is not recommended for smaller class rooms like 204 and 205. Works best in 203 or during evening hours in the hallway.
