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.

If you find yourself away from a city, spend an hour looking up on any clear, moonless night. You’re bound to see a few brilliant “shooting stars.” These actually have nothing to do with stars: They’re meteors, and if your viewing conditions are good, you can see about seven per hour on any given night.
Microwaves are low energy electromagnetic waves that have so little energy they can’t trigger chemical reactions in the molecules they encounter.
