In this activity, learners try to blow up a balloon hanging inside of an empty bottle.

In this activity, learners discover a trick to release the air out of a balloon without popping it.

In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass.

In this activity about phase change and condensation, learners boil water in an empty pop bottle in the microwave.

In this demonstration, learners observe the effects of density and pressure. A "diver" constructed out of a piece of straw and Blu-Tack will bob inside a bottle filled with water.

In this activity, learners investigate how changing the center of gravity of a balloon affects how it travels. Learners fill a balloon with a little bit of water and insert into an empty balloon.
