An adhesion tester is a special tool that helps us check if things stick properly to each other. Like when we use glue or tape, we want to make sure they will stick well and not come off easily.
With an adhesion tester, we can test how strong the stickiness of something is. The tool uses a small piece of material that sticks to the surface we want to test, and then we pull on it to see how much force it takes to pull the material off. If the material comes off easily, it means the stickiness is not very strong.
For example, imagine we want to stick a sticker on a wall. We can use an adhesion tester to check if the stickiness of the sticker is strong enough to stay on the wall. We stick a small piece of material onto the sticker, and then we pull on it to see if the sticker comes off easily or if it sticks well.
Overall, an adhesion tester helps us make sure that things stick together properly, so that we can trust them to stay in place when we need them to!
