Curvature of Space/Time

Visualize gravity in space with this very unique device.

A framed oval of Spandex fabric, whose shape is distorted by position masses, serves to simulate the gravitational behavior of objects. Two masses and two balls are provided to demonstrate plausible orbits around one-mass and two-mass systems in a very tactile way. Using the large and small steel balls, the mutual attraction of any pair of masses is easily demonstrated. Takes a bit of practice but is well worth the effort to demonstrate a concept typically difficult to visualize.
