WebFoam tubes (Available at most hardware stores.) Masking Tape. You can build a roller coaster from the foam tubes that are often used for pipe insulation. Cut the foam tubing in half and you have a track for a marble to roll down. The foaming can be taped on the wall (using masking tape) and moved around to make a roller coaster.

Quantum gravity models predict that space-time is a seething foam of tiny regions where minisculenew dimensions unfurl and then furl back in on themselves, spontaneously ... WebThe foam rocket flies ballistically. It receives its entire thrust from the force produced by the elastic rubber band. The rubber band is stretched. When the rocket is released, the rubber band quickly returns to its original length, launching the foam rocket in the process. Technically, the foam rocket is a rocket in appearance only.

WebWelcome Boulder School for Condensed Matter and Materials Physics WebApr 9, 2005 · The question is how does the quantum foam arise out of the structure of spacetime, or visa verse. Perhaps the structure of spacetime is a prerequisite for the formation of virtual particles. It seems obvious that you cannot have particles without a spacetime as a background in which to describe the particles.
