Lycra sheet + support + massive balls = "Gravity Visualized"

Neat "rubber sheet" analogy of the curvature of space time on YouTube. Skip to 5:57 for orbits around the Earth moon system if you don't have time to see the whole thing. Would have been nice to see that demo as a kid.



Url of the 5:57 mark,
