Paper power This shows how the perceived properties of a material can be altered by using it in an unexpected way. Show your audience a jug of water sitting on an A4 sheet of photocopy paper. Challenge them to remove the paper from under the jug, without spilling the water or touching the jug. (Attempts to quickly tug the paper from under the jug tend to result in water spillages, so do this in a suitable place and have some dry sheets of paper to hand for further attempts.) In the event of failure by the audience, demonstrate how, by rolling up the paper from one edge, you are able to push the jug along with the paper tube, and ultimately off the paper. | ||
