In this physics activity, challenge learners to lift a book with just air using a plastic bag and a straw. This activity demonstrates compressed air and forces.

Balance a ball in the air with a hair dryer! This Exploratorium produced activity shows learners concepts like lift and air streams. You can try many different angles, speeds, and ball types.

In this activity, learners will observe how air interacts with a paper helicopter. Learners will test different variables of weight, size, and shape.

In this activity, learners explore motion and airflow by setting two aluminum cans on their side and blowing air in-between them.

Conduct a simple experiment to explore how temperature changes can make things expand or contract.

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.
