Just how do bugs walk on water? Learn how bugs use their feet and surface tension to walk.
Heat was once thought to be a liquid. However, we know know that heat is a measure of kinetic energy.
Slipping on ice is no fun. But, why is ice, technically, not slippery?
If you've ever driven on a highway during a heavy rain, you know about the danger of skidding. Learn how tire tread works on this Moment of Science.
Have you ever gotten a callus and wondered what is was?

As you fill a flat tire from your hand pump, you notice parts of the pump getting hot. Why would the pump get hot with all that cool air flowing through it?
You’re out on a clear, starry night with your best friend, looking for shooting stars. Look, there’s one, your friend shouts, but by the time you look, it’s gone. There’s another, she cries. Too late, you missed it. Then one comes along that seems to just amble across the sky, nice and slow. Why is it that some shooting stars are so fast and others are much slower?

There are some balls that are specifically designed not to bounce. The question is, how do these so-called 'dead balls' not bounce?
Water bugs manage to stand on the surface of a pond, because the pads of their feet resist contact with the water just like wax paper does. This allows the bug to rest on the thin film of surface tension that naturally covers the pond. This surface tension film is caused by the strong attraction the surface water molecules have toward each other, as well as toward the water beneath them. Learn more on this Moment of Science.
