Bill Nye The Science Guy bikes down a long road in wide open country to demonstrate a scale model of the solar system – a classic clip. Total distance of his ride to Pluto, back before Pluto was known as a dwarf planet: almost 2.5 miles (4 kilometers).

If you’ve seen physics teacher Dan Burns demonstrate how to use stretched spandex lycra to explain gravity and spacetime, then you’ll like this Fabric of the Cosmos how-to video from the 2012 SPS SOCK (Science Outreach Catalyst Kit). Meredith Woy and Melissa Hoffman build the model and then demonstrate orbits, tides, roche limits, and the creation of the solar system.

Physics Teacher SOS workshop leader Dan Burns demonstrates how he uses stretched spandex lycra, weights, marbles, and gravity in his high school classes to make this impressive space-time warping demo. Filmed from afar, this general relativity explainer was made for other educators, but my kids were riveted by these tangible representations that include how our planets orbit the sun, how the moon orbits the Earth, and the free return trajectory used in the Apollo Program.

Update: See how to set up this excellent demonstration in this Fabric of the Cosmos how-to video.
