how can i make co2 easy?

Question

ok well i am trying to make cheap dry ice but i need lots of co2.
or f anyone knows how to make dry ice easy

Answer 1

breathe out

Answer 2

WELL, this is an industrial process:
Basically, dry ice is frozen carbon dioxide (CO2). CO2 is usually found as a gas -- it's what we exhale. To make dry ice, CO2 is compressed, and it liquefies at a pressure of approximately 870 pounds per square inch. The dry ice press then reduces the pressure, and part of the liquid CO2 sublimates (meaning it turns from a solid into a gas). The remaining liquid freezes into flakes that are compacted into solid blocks. The resulting dry ice is denser, heavier, and colder than ice made from water.

Answer 3

It's more cost effective to purchase dry ice however; for a low cost alternative to making dry ice blocks you can even make dry ice snow yourself with a CO2 tank. Although it is not very efficient, just open the hose into a burlap bag, and then pack the dry ice snow into a container. This can be used to fill coolers, quick freeze food products before shipment, science projects, and many of the same uses as traditional higher density blocks of dry ice without the expensive hydraulics and capitol costs of a large dry ice maker. It will also save on storage loss through sublimation as it is only used when immediately needed

Answer 4

the commercial gadget that uses liquid co2 from a tank at 900 psi to make CO2 in a solid form (dry ice) uses twice the weight of liquid to make a weight of dry ice. It really is difficult to make dry ice in a solid block and requires that the co2 produced be compressed.You might be able to scrounge dry from your local red cross or hospital towards the end of the day. They use dry ice to ship fresh blood and let it evaporate overnight. (The cheapest solution to your problem. ) Making a cloud chamber for cosmic ray or nucular particle viewing?

Answer 5

A regular freezer does not go near cold enough to make dry ice. It needs pressure also. Vinegar and baking soda produce CO2.
Any carbonate will give CO2 when acid is put on it.

Answer 6

Dry ice is not ridiculously expensive to begin with really.
