Rocket-Powered Red Wagon of Science Posted by: dcolarusso Video duration: 12 seconds There's only so much momentum in the world. Our pilot starts with none, momentum being the product of mass and velocity. Then suddenly, it seems, there is momentum where once there was none. The CO2 sprays backwards with a sizable momentum, and nature compensates, propelling the wagon forward and assuring the two add up to zero. Thanks conservation of momentum.
