In Thailand fireworks are taken seriously!
Why not send a simple rocket up to the skies?
You may also take a giant spinner wheel and put some rockets on there. The chemical energy is turned into heat, heat into movement of the wheel. Once the wheel turns fast enough the propellors in the wheel generate lift: the wheel soars up to the skies thus having the last energy conversion: from movement into gravitational energy.
So again why not send a simple rocket up to the skies?
Sending up these “Girondolas” is smply more more fun!
BEWARE! building and firing these units is not without danger! They may explode befor takeoff injuring operators as well as spectators.
Yo will get the idea after seeing the video below:
