Dry Ice Tip

This weekend we had a Halloween party. One of the little touches was a cauldron of simmering witches brew, complete with dry ice.

I got the dry ice at a local market that stocks it for Halloween. The block was too big to fit in the cauldron so I stuck half of it back into the freezer for tonight.

Katy went to get it out but found nothing but an empty bag. Whoops! Carbon dioxide sublimates when it's warmer than -109.3 degrees Fahrenheit - and my freezer definitely qualifies.

So, be sure to buy dry ice the day you're going to use it - and use it the day you buy it.
