DeVargas Middel School

This time when we went to the middles school, we decided to do a more interesting session which means only one thing: hands-on experiments. Kristen came up with the ideas and the material purchases were made; thus prepared we went to the school. The first experiment was to make a non-Newtonian fluid, which is a fluid that doesn't act like one the way a tradition fluid should. For example, if you punch it or ht it with some force, it will act like a solid; however if just move your fingers around in it slowly it acts just like a liquid. Add some food coloring and the students and some of the WPI students were having a lot of fun. To cap off the experience, we decided to use the Diet Coke and Mentos experiment, specifically we created bottle rockets out of them. Steve was elected dropper of the Mentos, unfortunately for him, he was not quite quick enough to drop and dodge and as a result, was completely soaked with the resulting foam explosion causing him to smell of mint and Coke for the rest of the day.
