The past few weeks we had been preparing for a spooky science day to show off to 1st and 2nd graders. We had to research and test experiments that were related to Halloween and had to do with science! Logan and I were inspired to do our experiments from videos of Steve Spangler! We thought “What screams more Halloween than a Jack-O-Lantern!?” So our first experiment was carving a pumpkin the scientist way! This consisted of me carving the pumpkin at home, but the pieces that I cut out were placed back in their spots. I then cut a small hole in the back, just large enough to put in a lighter. The day of the experiment we would place a beaker of water inside of the pumpkin and have the pieces (eyes, nose, and mouth) back in there original spots so that it looked like a normal pumpkin. We then placed about 7 rocks of Calcium Carbide into the water. After that we placed the top back on the pumpkin as we waited for the gasses to build up inside. With the countdown of the kids, we placed the lighter into the small whole in the back and light it. This caused a small explosion inside of the pumpkin sending the carved out pieces air borne. Leaving a perfectly good Jack-O-Lantern.
