Introduction: Make Edible Ice Spheres With Cryogenic Liquid

My most delicious project yet. The mixture of dry ice and alcohol that I use in this video forms a liquid at a temperature well below -100 degrees Fahrenheit, easily capable of freezing anything containing moisture. There is a possibility of frostbite if the liquid is in contact with skin for any more than a second or two, so great care must be taken. Tongs can be used to safely lower the balloons into the mixture. To cool the alcohol, dry ice should be added to the bottom of the water cooler first, then the alcohol slowly poured in over it. Dry ice should never be dropped into a pool of alcohol unless the alcohol is already very cold or else the dry ice will evaporate quickly and the rapid boiling will cause the container to overflow. Isopropyl alcohol is flammable so care should be taken to avoid flame and have adequate ventilation. It is also not an edible type of alcohol, so care should be taken not to get any into the drink.

So far as I could find this is the original video responsible for the idea of alcohol cooled by dry ice. Very useful idea for a huge number of projects! http://www.youtube.com/watch?v=d11TFkeqbwY

This is only my second project involving food & drink so let me know your thoughts!

    Hello, how long can the partially frozen structures sustain? Can I make them the day before and the integrity be preserved for the next day or do I have to make them a la minute so to speak, day of?

    Wow! That is Incr-Edible :)

    Just a thought....wouldn't ethanol be a better, albeit more expensive, alternative?

    Looks really really cool!

    I was wondering if you could share from your experience - how would you advise on preparing these things in advanced (i.e. night before a party)?

    It would be hard to prepare them very long before serving. In a freezer they will freeze all the way through so that's no good. The only option really would be to drain the liquid out of the center of the shells and store them that way to be refilled later. Whatever they are filled with would have to be chilled also so it doesn't melt the shell instantly.

    Robinson Crusoe is also my fav book!
