The hot air increases the pressure in the glass and forces some air to escape between the balloon and the mouth of the glass. Immediately after the flame goes out, the air begins to cool, contract and the air pressure drops. The drop in air pressure creates a low pressure inside the glass. Now the higher air pressure that is outside the balloon begins to try and fill the lower pressure jar and pushes the balloon into the glass. in the process. • #baloon #airpressure #heat #experimemts #science101 #education
