If someone told you to buy nitrogen ice, smoke ice or fog ice, the thing you need is dry ice. Here is the difference, in plain words.

How to tell which one you need
- If you want white fog on the floor, or goods kept frozen in a box, you need dry ice.
- If you need a liquid poured from a flask for cryogenic work, you need liquid nitrogen, from an industrial gas supplier.
- If things only need to stay cool and must not freeze, ordinary ice or gel packs will do.
