Movement of massive objects in space create gravitational waves that travel outward in spacetime and bend light along the way. We detect these waves by using lasers and watching changes in how light moves through space. This demo uses clear jello and a laser to show how collisions create ripples that radiate outward from the source, which are able to bend light.
Tuning forks are one of the few instruments that resonate with one distinct frequency. Create a workshop with tuning forks with this variety of quick, fun demos ranging from visualizing sound with lasers, to watching energy transfer through pendulums.
This surprising demonstration illustrates the relationship between densities and buoyant forces.
This demonstration provides a visual for how the diversity of matter affects interactions between different materials. The participants will be able to view a visually striking, easy-to-assemble display of various solids and liquids that tend to separate from one another due to their densities. The demonstration goes on to explain how this relates to the different states of matter, and makes a mention of the buoyant forces responsible for making objects float.
