Curvature of Space and Time
A framed oval of Spandex fabric, whose shape is distorted by positioned 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 masses is easily demonstrated.

Density Ball.
Our density ball is used demonstrate the effects of temperature and mineral content on density. The metal ball will float in cold water, and sink in hot! The density of water is not constant but depends upon several factors. The effects of salinity and temperature play a large role in the flow of earth's ocean currents. The 30-166 Denstity Ball can be used by varying salt content as well as temperature, to show the effects on density.
