How Does Don't Put Wet Rocks In A Campfire Work?

Don't put wet rocks in a campfire because they can make the fire go out or even cause a little boom!

When you have a rock that’s been sitting in water or rain, it’s like a sponge, it’s full of water inside. If you throw that rock into a campfire, the water starts to get really hot, and it turns into steam.

Steam is like invisible water that pushes outwards with force. When there's too much steam in one place, it can push the fire apart or even make it go poof, just like when you pop a balloon!

Imagine you're making a sandwich, and you put wet bread into a toaster. The water turns to steam, and your toaster might not work as well, or maybe it makes a little puff of smoke! That’s kind of what happens with the fire.

So, just like you wouldn’t want wet bread in a toaster, you don’t want wet rocks in a campfire, because they can mess up the fire and make it go out.
