How to make crystalclear icecubes :-)
You want to shoot drinks with nice and clear ice cubes but you don't want to shell out a fortune for acrylic cubes?
Here you go, from left to right:
1. Cloudy, ugly icecube---we can do better!
2. A styrofoam mold guarantees isolation at the bottom
3. Filling that mold with water serves as thermal coupling
4. Now: boil destilled water, then let it sit, until it is handwarm
5. Fill the icecube tray
6. Wait approx 15 h, and then enjoy your clear cubes :-)
The trick is the "directional" freezing. If the ice freezes from all sides simultaneously, the air cannot get out and the ice gets cloudy. If you insulate one side, this is not the case.
The boiling boils out enclosed air,
the usage of destilled water guarantees clean water.
Piece of cake! :-)
