This Rocket which can fly powered by compressed air up to +30m high !

What you need :

• The printed rocket
• some plastic electrical tube 13mm interior - 15mm exterior
• a compressor

I've tested it up to 10 bars with a rocket printed in carbon PLA 0.20mm strength and it flew very high. I do recommend to limit compressor pressure to 5 bars for kids and supervise usage !

This can be dangerous, use at your own risk !

You can also just blow with your mouth in the electrical conduit and send it 5 meters away, that's much more safe…
