In need of bubble makers !

[Externet]

Hello.

 

Do you know of any inorganic compound in powder form that becomes gas when triggered by an 'stimulus' like light, microwaves, heat...

 

Like every particle of the powder release or turn to gas ? I want to make bubbles, megazillions of them...

 

How is styrofoam made? Is it by mixing two chemicals or by external stimulus ?

[John Cuthber]

Bicarbonate of soda gives CO2 and H2O on heating.

[hermanntrude]

decomposition of H2O2?

[John Cuthber]

H2O2 isn't ordinarily a solid, did you mean percarbonate or some such?

[hermanntrude]

oh crap... missed that bit.

styrofoam is made by mixing polystyrene and a solvent in an extruder (the mixture is at high pressure/temperature inside the extruder).

 

When it leaves the extruder, the pressure becomes atmospheric, and the solvent which is inside the polystyrene expands a lot, and the polystyrene becomes the foam (with the solvent gas in the air-pockets).

 

then you have to leave it for a while so that air can replace the solvent in the air-pockets in the foam.

 

But styrofoam is organic... not inorganic.

Found something, but still do not know what compounds are they
