Halloween STEM

We did a little kitchen chemistry to make fluffy slime. We used pva glue, water, food colouring, shaving foam, baking soda and contact lens solution. It was great fun! Follow this link for the process: https://youtu.be/is8SgaQfrZ4

Next we inflated a spooky balloon without using our breath to blow it up. Instead we put vinegar in a bottle and a teaspoon of baking soda inside a balloon. When we placed the balloon over the lid of the bottle the powder dropped into the vinegar and caused a chemical reaction. Gas was created which inflated the balloon a little. We wanted a more impressive result so we added a little more baking soda (2 tablespoons) and boy did it work! We were a bit surprised by how quickly it inflated. Perhaps we put a little too much in, but it was very exciting to watch! 👻
