Stumbled upon a Wiki site that I thought was extremely interesting.
Did you know that there’s a record of stones that move by themselves? Called the "sailing stones", "sliding rocks", or "moving rocks", these can be found in Racetrack Playa in Death Valley, California. Nobody knows why these move: the rocks are too heavy to be moved by wind. Other factors are also not considered, since if water or anything else moved them, the tracks of the rocks would’ve been disturbed. They also couldn’t have been moved by humans, because the footprints would’ve appeared on the ground pretty easily (the soil/sand is such that anything that happens on the surface level would leave marks on it).
You can read more about it here.
So is that why the place is called Racetrack Playa? Because the rocks race each other?
Fireflies don’t really turn on lights when they light up. Instead, they release an enzyme called luciferase and ATP, and these, when exposed to air, create a chemical reaction when it is combined with oxygen to create that glow.
So the next time a kid comes up to you and says that the firefly’s producing light, your answer should be, "No, honey. That’s simply a chemical reaction produced when luciferase combines with oxygen!"
