Dry ice was discovered rather than invented. It was first discovered by Charles Thilorier a French chemist in 1834.

a molecular solid...
Nobody created dry ice; it occurs naturally.Dry ice is frozen carbon dioxide. Carbon dioxide is a gas in our atmosphere created by animals (we exhale carbon dioxide) and chemical processes (fire creates carbon dioxide, so any fuel-burning process like running a car generates carbon dioxide).Carbon dioxide freezes at -78.5 degrees Celsius, or about -110 degrees Fahrenheit. Frozen carbon dioxide at atmospheric pressure (normal air pressure) doesn't melt like ice does. Most familiar solids (like ice) melt into liquid (water), and if we heat them even more we can boil the liquid into gas (steam). But liquid carbon dioxide isn't very stable at low pressure - the forces that hold the molecules together in liquid form are very weak, and unless the molecules are forced tightly together by high pressure they will fly apart into a gas state.This is why dry ice makes a fog: it goes from a solid directly into a gas form without ever becoming a liquid. This process is called sublimation.Dry ice is natural, but it doesn't naturally come into those nicely shaped blocks and pellets. There are plenty of factories that specialize in making dry ice in bulk and selling it. Nevertheless, no human "created" dry ice.

Simple. You keep ice in dry ice. But be careful not to eat dry ice!
Dry ice is frozen carbon dioxide.
Yes, dry ice is opaque.
Do you sell dry ice
Dry ice freezes and the wet ice and everything keeps cool and chilled but not frozen..obvousliy.
Yes ice fishing was discovered in 1915
Dry ice is solid carbon dioxide (CO2). It is called dry ice because it does not melt when it heats up, it goes directly from solid to gas. It is NOT the same as ordinary ice, which is of course, solid water. Dry ice is much colder than ordinary ice.
