Jetpack Rocket Science
Check out 2Veritasium! http://dft.ba/-ve2 MinutePhysics has a great video on Milkman, vomiting levitator: http://dft.ba/-vomphysics Jetpacking was awesome fun! Despite the fat lip I had a great...

This is a water jet pack... but no, that's not me flying it. This is me. It's harderthan it looks, ok? But to understand how it works, we need to first talk rocket science.Rocket science is meant to be one of the most complicated things in the world, but the basicprinciple is incredibly simple. It's just Newton's 3rd law -- all forces come in pairs,which are equal and opposite.To demonstrate this, I'm using a fire extinguisher on a skateboard. As the carbon dioxide isforced out the back of the extinguisher, it puts a force forwards on me causing me toaccelerate.Or that's the theory anyway.If you look closely, you can spot the exact moment I realize this is a fail.So what was the problem here? Well the force applied to ...
