Dry is is frozen carbon dioxide gas. You *can* put it in your drink. When you see somebody mix a dangerous potion on TV where there is a white vapor rising from the glass. That is done with dry ice. Don't touch the stuff though or you risk a freeze burn.

Ordinary ice is made of frozen water while dry ice is made of frozen carbon dioxide. At room temperature, the ordinary ice melts to form water, but dry ice sublimes and converts to gaseous form instantly. That is why it is called dry ice, you do not see any liquid.

Ice is water that has changed form after being subjected to temperatures below 0 Deg C. Any temperature below 0 Deg C will create ice out of water, but the temperature of the ice itself will not be reduced beyond a specific floor (minimum) for elemental reasons.
Dry Ice is a chemically purified or alchemically created gaseous substance called Carbon Dioxide (found in air), that when treated can be converted to a liquid form for ease of transportation. After further convertion immediately before use, it can be made to change form again into a solid. Being that it's original state is gaseous, when subjected to normal environment it gives off gas. It only maintains it's form when kept at roughly -50 deg C, whereas the liquid can be stored at more reasonable temperatures, and the gas at room temperature.
Dry ice can give freeze burns if held by unprotected hands for a few seconds, whereas ice will freeze burn if held by unprotected hands for a few minutes.
Dry ice will eventually evaporate into the air leaving no trace of it's existence over time in room temperature. Ice will melt into a liquid in room temperature, then evaporate if subjected to temperatures over 100 deg C.
Both substances are naturally occuring base elements, one being an amalgam of Carbon (Earth) and Oxide (Air), whereas Ice comes from Hydrogen (Air), and Oxygen (Air), however although both water and carbon dioxide occur and exist naturally, only ice of the two solid forms occurs naturally. Dry ice must be manufactured.
Dry ice is used in many manufacturing plants. Because it is a basic substance, and very pure, it is considered safe to place in direct contact with edible human foods, without any of the complications surrounding the water that ice leaves. It is used in the transportation of foods that require being frozen solid to maintain freshness, and is considered safe for handling within reason for anyone in the industry.
Dry ice can be thought of as a half way option between ice and liquid nitrogen, a substance many times colder than dry ice. For comparative purposes, liquid nitrogen would realistically freeze a human limb solid in a few seconds.
Good luck with your research. :)

Dry Ice is a very cold temperature: -109.3°F or -78.5°C.
Normal, everyday ice is about 32 Degrees F.
Difference of about 150 degrees F from my calculations.

Dry ice is solid carbon dioxide, while ordinary ice is solid water.

Dry ice is a chemical used in labs. It can be very dangerous and you cannot put it in your drink.

Would you eat a dry ice? If yes, then,...
...good luck!
