Totally awesome this guy demonstrates a water powered jetpack which really works.  It is based on Newton’s third law but instead of using propellant it pumps out a massive amount of water per minute using a jetski as a pump.  It is still a form of rocket science albeit a simpler demonstration.  “All forces come in pairs which are equal and opposite”.  The first demonstration of the principle happens by using a fire extinguisher and a skateboard.

Learn how he does this in the video on the next page
