Burl

Burl is a type of wood that is very special because it has these weird lumps and bumps growing on it that make it look like a crazy tree monster! These bumps happen when the tree tries to heal itself after getting injured or sick. It's kind of like when we humans get a bump or a scar on our skin.

People really like using burl wood because it looks so interesting and unique. They can make all sorts of things out of it, like furniture, bowls, and even musical instruments! But cutting into burl wood can be tricky because the bumps make it harder to work with.

Overall, burl is a special type of wood that's super cool because it has these funny lumps and bumps that make it stand out from other trees.
