AWESOME! No other words for this experiment. We all know what’s going to happen, but when. If your bored and have nothing to do then this experiment will add some excitement to your afternoon.
What happens inside the bag is a chemical reaction – the baking soda and the vinegar eventually mix (the paper towel buys you some time, as it’s like a fuse) When they do mix, you create an ACID-BASE reaction and the baking soda and vinegar work together to create a gas, (carbon dioxide) The carbon dioxide starts to fill the bag, and keeps filling the bag until the bag can no longer hold it any more and, POP! We used a liter/quart bag and as you can see it took a little longer to fill. Try using a sandwich bag, as I’m sure it will not take as long. Happy popping!
