A glue stick is like a magic wand that helps things stick together. Imagine when you play with play-doh and you want to stick two pieces together, you squeeze them and smush them until they stick. A glue stick helps you to do that without making a mess.
Basically, when you use a glue stick, you twist the bottom part to push the glue out of the top. The glue comes out like a soft, sticky paste that looks like Chapstick. Then, you rub the glue on one of the things that you want to stick together. After that, you press the two pieces together and hold them for a little while. And voila! You have stuck the two things together.
Glue sticks don't dry out quickly, which means you can work slowly and be more careful about fixing things. It's important to remember that glue sticks work best on paper, cardboard, or other light materials. They won't work very well on things like wood or metal.
Glue sticks are also very easy to clean up. If you get some glue on your fingers, you can wash it off with soap and water. Glue sticks are a wonderful invention and they make art and crafts projects much more fun and creative!
