- Heavy objects placed on giant spandex sheet curve fabric.
- Trajectories of rolling marbles on spandex sheet are affected by curvature of sheet. (mostly they are affected by earth’s gravity… but the analogy gets the point across)
- youtube video of this demo, with classroom ideas.
- Demo can be set up in lab room, to accommodate audience participation.
- Curvature of spandex proportional to mass of ball; amount of deflection of rolling ball affected by curvature of spandex.
- Located in L01, in between sections A2 and B1.
