Activity to illustrate atmospheric pressure

Answer 1

Hold one balloon by the string in every hand and role the two balloons so that they are at your nostril level and 6 inches apart. Blow challenging into the area between the balloons. This lowers theair pressure. The pressureof the surrounding air is now higher and it will push the balloons together.

Fountain Bottle.
Take a long straw and insert it in the mouth. Wrap a lump of clay around the straw to form a seal. Blow hard into the straw—then stand back. Your blowing increases the air pressure inside the sealed bottle.
