In packing dry ice, make sure to use well insulated coolers, preferably those with automatic ventilation. In packing make sure to place the clocks or slabs of dry ice as close to each other as possible to avoid empty space. The empty space can cause the dry ice to sublimate faster. Fill in these spaces with new bubble packs, newspaper or Styrofoam peanuts.

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.
You will have some dry water sodium. Salty dry ice.
If you mean the dry ice bomb as in putting dry ice in a bottle and sealing it, and then having it explode, then no. The bottle and the dry ice cannot be reused from the Dry Ice Bomb. The reasoning is that the Dry Ice would have already used enough of its fuel to try to explode the bottle that no fuel is left to explode another, and the bottle would be ripped in half by the Dry Ice inside, so the bottle cannot be reused.

To reduce dry ice loss, make sure to pack dry ice as close to each other as possible. Fill any empty space with new bubble packs, newspaper or Styrofoam peanuts since the space will cause the dry ice to sublimate faster.
Ice is fine. My frozen meat lasted 50 hours
No, you cannot. Cryovac it, pack it in dry ice and Fedex it or something.
Dry ice evaporating is endothermic-->+DeltaH A sparkler burning is exothermic--->-DeltaH The reaction that occurs in a chemical cold pack often used to ice athletic injuries is endothermic--->+DeltaH
Dry ice packs cool on their own as they sublimate from a solid to a gas. To help expedite this process, you can place the pack in a well-ventilated area or expose it to warmer temperatures. Never seal dry ice packs in an airtight container, as the buildup of gas could cause the container to burst.

Energy is transferred from an ice pack through the process of conduction. When an ice pack comes into contact with a warm body, heat is transferred from the body to the ice pack, causing the ice to melt and absorb the heat energy.
Heat will travel from the person's hand into the ice pack, where it will excite the molecules there and warm the ice pack.
Thermal energy will flow from your hands to the ice pack, since your hands are warmer than the ice pack. This will cause the ice pack to absorb heat and melt slightly.
Yes an ice pack does cause redness from cooling the skin.
Dry ice is frozen carbon dioxide.
Yes, dry ice is opaque.
