Boat and siren more gas pressure

Warning take off headphones, hands on ears when you see the notice, the second half of this video is very loud, air pressure makes sounds.

Adrianne also brought a putt putt boat, the water vapourises to steam which as a gas tries to expand to fill a larger volume, but being contained instead becomes pressurised until it can pushes out the water, providing the locomotive force for the boat.

Sound is pressure waves in the air, sometimes sound waves are so loud we can feel them through our skin.

Why not google air pressure and see if you can find some youtube videos with more ideas about air pressure.
