Vertical Rocket Sled v3

So moving on from the sled, we tried to launch it vertically

…that was interesting…

Clearly the rocket is too heavy to take off, but once it looses weight it takes off. So, a couple of things to try on the next iteration:

• Bigger nozzle – maybe a cork instead of nozzle
• Smaller rocket
• Get the centre of gravity in front of the centre of pressure
