Egg Crush

This demonstration dramatically shows how not just the strength of a material, but how it is designed, is important when withstanding forces.

Fabric of the Universe Part 2

After completing Part 1, explore solar system formation, tides, and planetary rings using a spandex sheet.

Straw Oboe

By constructing a simple straw “oboe,” participants learn about sound waves and closed pipe resonance. 

Marshmallows & the Speed of Light

This workshop uses marshmallows to teach participants about waves and to calculate the speed of light. 

Light Fountain

This demonstration shows how light changes paths when travelling through different materials. Snell’s Law and the critical angle are explored using lasers and water. 

Hair Diffraction

Participants use a hair to show how light can interfere to produce a diffraction pattern.     

Fabric of the Universe

Explore forces in a gravitational field using a spandex sheet and marbles.

This demonstration shows how gravity can be interpreted as the bending of spacetime due to massive bodies. Participants can identify gravity interactions, observe how the shape of the spandex corresponds to mathematical models, and make inferences based on object size, shape, and mass.

After completing this demonstration, present Part 2 to explore solar system formation, tides, and planetary rings.
