Ask your chemistry teacher.
ice is slippery and dry ice is not because ice dosent dry out when the sun hits it and dry ice does!

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.
Solidified Carbon Di Oxide is commonly known as dry ice. At temperature below -78.5oC, carbon di oxide converts into dry ice through sublimation.
The dry ice was not known by alchemists.
Dry ice is frozen carbon dioxide, which is not a poisonous substance. You could, of course, get frostbite from it, but you could not be poisoned by it.
You could bring a small insulated container with some dry ice - a pound or two should do it. Make sure that the smoothie cup can fit before deciding on which cooler and protect the cup from direct contact with the dry ice. You could bring along a different container in which to pour the smoothie if it might travel better. The rules for dry ice vary with each airline, so check with your carrier. Remember that the cooler will likely count as a carry-on.
Use modeling clay to shape a volcano, then fill it with water and when you are giving your presentation, drop dry ice in it, it will begin to make fog.

No, you cannot burn coal over dry ice. Though they say that dry ice "burns" it doesn't really. It is extremely cold, and if you were to touch it, (which I highly advise that you do not do) it would feel like it was burning you. So, you could not actually get coal hot using dry ice.

You could put Icy Hot on the teachers bathroom toilet seats. Put dry ice in all the stalls.(probably not the best idea.)
Water ice can not do very much that dry ice can't do. The main things it can do are:Keep things less cold than dry ice. This could be good if you don't want to over freeze the food in your cooler.Keep drinks cold without carbonating them.Can be eaten by a human.Can be made for MUCH less money.EDIT:It can melt. Dry ice can only sublimate.
If a person took dry ice into his mouth, he would kill all the tissue that the dry ice touched, and could possibly die. If you even touch dry ice, it is so cold that it feels like it is burning you. Imagine what it could do to the thin, sensitive tissues in your mouth and throat.

Yes, dry ice is opaque.
Dry ice is frozen carbon dioxide.
