A physics teacher in the USA Dan Burnes adapted a presentation explaining/visualizing Gravity. Using less than $100 of materials he has been able to explain a theory/force that stumps the best of us. I just wish I had a teacher like him when I was in secondary school or university - physics would have been a lot more comprehensive and enjoyable.
I hope this video encourages and inspires others to create their own universes and discover what happens when you play with the space time continuum, gravity, spandex/lycra pvc tubing, marbles, weights and other spheres.
I can't wait to see what students, parents, teachers, tutors, colleagues come up with and I hope they video their universes at play and post them for all of us to see.

P.S: I can't believe he did that to my bike shorts, lol :D
