cylonlover writes: Looking for a more effective solution to the all-too-common wobbly table dilemma than a folded up bit of cardboard or piece of rubber under the leg, University of Virginia physicist Lou Bloomfield created a new type of silicone rubber called Vistik – it's malleable enough to take on any shape when pressed, but is still resilient enough to offer support, as it gradually starts to return to its original shape as the pressure is released. The material could have many applications... beyond just steadying up wobbly tables.
Today's scientific question is: What in the world is electricity?
And where does it go after it leaves the toaster?
