Can you walk on water? A women tries to run across a pool of water and falls in. A big machine pours another liquid into the pool. Not only are people able to run across this fluid, but they are able to dance on it, carry other people across it, ride a bike across it, and play soccer on it... and they don't sink! The questions that I would ask about this phenomenon are: What is this material? Is it a liquid or is it a solid? How are people able to stand on it without sinking? Why did the bike sink, but the person didn't? Why doesn't water act like this fluid?
