• Institute of Physics
In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle. The marshmallows will...

\$1 - \$5 per group Ages 4 - adult Under 5 minutes
• COSI
In this physics activity, learners will investigate the strength of egg shells. They will attempt to stack books on top of inverted half egg shells to see how many they can hold, and the results...

1 cent - \$1 per group Ages 6 - 11 10 to 30 minutes
• The Exploratorium
In this demonstration/activity, learners observe as a regular size marshmallow is blown through a tube made from a manila file folder. The result is spectacular, and the process provides a great...

• Institute of Physics
In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge. Use this...

• Integrated Teaching and Learning Program, College of Engineering, University of Colorado at Boulder
Learners use M&MsĀ® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air. They compare the composition of the air next to a...

• Integrated Teaching and Learning Program, College of Engineering, University of Colorado at Boulder
Learners develop an understanding of air pressure in two different activities. They model the magnitude of air pressure as gravitational force per unit area, and they use cookie wafers to model how...

• New York Hall of Science
Take the two-straw challenge and discover how pressure affects vacuums! In this activity, learners experiment with drinking through one and two straws, comparing the amount of liquid they can drink...

• American Chemical Society
In this activity, learners heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water. Learners design their own procedure,...
