Liquid Cryogenics

Now that the insects and bugs have all but disappeared from the backyard, the boys haven’t been able to attempt more cryogenic experiments involving these poor, hapless creatures, and our kitchen freezer. One cold day one of the kids initiated the idea of seeing what would happen to oil if left overnight in the sub-zero temperatures. Knowing the outcome, I decided to add more variables so that a comparison could be made. We put out a bowl of water, a bowl of canola oil and a bowl where we mixed the two liquids. We then recorded what we discovered the next morning!
