Dancing Raisins

…. otherwise known as “The Great Gas Experiment” took place at our kitchen table today. The kids had fun watching the raisins “dance” in the glass of ginger ale, as the bubbles of gas carried them to the surface. When a few bubbles burst at the surface, the raisins would then sink to the bottom of the glass to begin their ‘dance’ all over again!

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!
