Fun with Dry Ice?

To keep dry ice from evaporating I think you have to wrap it up in a lot of newspapers and put it in a styrofoam cooler or something that's insulated. Don't seal it too tight or it might burst open. Don't use plastic - I forget why. You better look it up, because there might be more you have to do. I just can't remember it all.

I think you can make instant ice-cream with dry ice. I'm not sure if it was dry ice or liquid Nitrogen, you you can take a plastic zip pack, put full cream milk in it, add vanilla essence in it (and some sugar, if you wanna). Seal it, real tight. Now, take a larger zip pouch/bag and fill it with dry ice. Put the smaller bag into the larger bag, and keep shaking it. In a few minutes, you'll see that the milk is solidifying. Scoop it up, and enjoy your homemade ice-cream!

I have no idea how to make dry ice last longer.All I know is that it is would be lost in the air as it melts because it is made up of carbon monoxide in frozen state. You could still enjoy it by using it to as a power charger to all your used batteries to recharge it all.I have read in some columns that using some dry ice to recharge your batteries is very effective that the power when you buy it from the counter is actually restored as if brand new products.You can use dry ice store your ice cream keep freezing even without refrigeration.

If you look online you could find a way to make ice cream, there is a lot of information about it.

Dry ice I have never tried but I think sprinkling salt can make it last longer. Maybe you can give it a go. Same cooking salt I am talking about..thanks for sharing. have a wonderful day.
