Compressed air flying Rocket

This Rocket which can fly powered by compressed air up to +30m high ! What you need :The printed rocketsome plastic electrical tube 13mm interior - 15mm exterior (double check the external diameter of your tube)a compressorI'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… Tube example : https://www.amazon.fr/sourcing-map-Plastique-Artisanats-D%C3%A9coration/dp/B09JSR6B86/compressor example : https://www.amazon.fr/Einhell-4010495-4010495-compresseur/dp/B07KY6M95P You can also use a hand air-pump with some kind of adaptator
