Heating air causes it to expand. This demonstration shows this as well as how a difference in air pressure can crush a plastic bottle. Playing with equipment like this kids can start to wonder about the phenomena behind them. Focused on middle school science these activities are good for many levels and require minimal equipment. Studying air pressure is a good precursor to studying buoyancy and density #airpressure
