chemical reaction pneumatic?

Unread postAuthor: djt » Sat May 27, 2006 12:36 pm

has anyone used two chemicals that produce a large quanity of gas to fill a pneumaic chamber? i dont even know if there are two chemicals that produce enough gas to fill a chamber to a resonable psi for launching things. if there are though it would make pneumatics more portable.

You could use dry ice in your pnematic, you would have to measure the psi closly thuogh, and it isn't two chemicals, but you don't need a compressor.

Correct, H2O2 is indeed an oxidizer. Actually, they use it in rocket engines as the O2 source.

You could try baking soda water and citric acid (the water is to let them mix like baking soda and vinagar but vinagar is already wet and that mix is way more powerful than baking soda and vinagar).
EDIT: you could use it with a burst disk but you would have to always have it aimed until it fired.
