We need :
- basin with a large rim
- strip of fabric
- graduated cylinder
- weighing scale
- small dish
- solide carbon dioxide
- dish soap
Caution!!! The ice is very very cold at -78.5°C!!!
Stir sugar, glycerin, water and dish soap with spoon. Fill a basin at 2/3 of water and put a piece of dry ice in a basin. Soak a strip of fabric in the mix and pass it on the rim of the basin.
The mix creates a single bubble on the rim of the basin and it seems the water is boiling. At around 40 seconds it explod.
The experiment shows different changes of states :
- The solid carbon dioxide becomes gas, it's sublimation
- The gas becomes liquid, it's condensation.
