Popping Fun: Class Response

In class, I had a great time "Popping Fun". The objective of the assignment was to make the cork hit the window. We had to combine baking soda and vinegar in a test tube, then close it using a cork. Our group was doing very well and we even hit the window twice in a row. If we had just hit the window one more time, we would have received ten extra credit points. I was the motivational speaker for our group and I believe I did a great job. What I learned in this experiment was that the high pressure and little volume inside the test tube caused the cork to pop out. Some keys to hitting the window were trigectory of test tube, correct amount of baking soda and vinegar (Which I found to be 16 mL of baking soda and 10 mL of vinegar), and motivational support!
