Well, our lesson last Tuesday was supposed to be growing bacteria. Unfortunately the nutrient agar Mrs. Owen ordered did not make it to class in time. Of course, it was delivered to the school shortly after our club had met. Go figure!
Instead, we occupied our time by seeing if we could make bubble bounce! We tried a solution of dish soap and water, then tried to use another solution of dish soap, water, and glycerin. We blew bubbles using both solutions and tried to bounce them in our hands. It didn't work!
So, then we decided to put on a cotton glove. We tried both solutions again. We found we were able to bounce the dish soap and water bubbles a little bit, but they weren't very strong. The solution that contained glycerin was MUCH better! We were able to blow large, strong bubbles and bounce them for longer periods of time.
The reason we were unable to bounce the bubbles in our bare hands was because of the oils our hands contain. This causes them to pop. A clean cloth like a glove, or even your shirt, keeps the bubble clean and prevents them from popping. Try it at home! It's a simple magic trick to show your friends and family members!
