Dry glue

Dry glue is like the glue you use in school, except it's not slimy and wet. Instead, it looks like a little brown or white rock. When you want to use the glue, you have to add water to it to make it sticky!

So, let's say you want to glue two pieces of paper together. First you take a little piece of dry glue and put it in a cup or container. Then you add a tiny bit of water to it and mix it up with a brush or your finger. After a little bit of stirring, the glue will become sticky like the kind you use in school!

Now, you can take the brush or your finger with the glue on it and spread it onto one of the pieces of paper. Then you can stick the other piece on top of the first one, and press down firmly to make sure it sticks.

And that's how dry glue works! It might seem a little weird at first, but it's actually really handy because you can make as much or as little glue as you need, and you don't have to worry about it drying out in a bottle like wet glue can sometimes do.
