how to make a good slime
Chemistry is great for making many useful products. It's also good to make fun things just to play with. Let's make some mud!
1. Place a tablespoon of water in a small plastic cup. Add a teaspoon of borax. Mix until the borax melts as much as possible. This is your If you want your mud to have a certain color, add one or two drops of food coloring to the borax solution.
2. Place a tablespoon of water in another cup and add a tablespoon of Elmer glue. Add the mixture with a lollipop stick until the glue and water are mixed well. This is your glue solution.
Pull the mud out of the cup
3. Slowly pour all of the borax solutions into glue solution, and stir with a clean lollipop stick. You should notice a sudden change in solutions.
Your muck is done when you pick up a lollipop stick and most of the mud comes out on the stick.
4. When you have some nice thick mud, pull it out of the lollipop stick and move it back and forth between your hands. The more you play, the less sticky you get.
5. Try dragging the mud very slowly to see if it extends.
6. Form the mud in the ball and see if it reverts. You can put it on the bottom of the inverted cup and watch it slowly flowing.
7. Try flattening your muck in a pie then knocking it from one edge to see what it does.
what are you expecting
As the borax and glue solutions move together, the mixture becomes thick. They are also attached to the lollipop stick. When you slowly pull out, your mud will extend. However, if you quickly drag it will break. The mud flows slowly, making it look like a liquid, but it can also bounce back, making it seem difficult.
What is going on there?
What makes the mud thick and silky?
The glue contains long flexible particles called polymers. These polymer molecules infiltrate each other as fluid.
In the water, the borax forms in the water an ion called the borat ion. When the borax solution is added to the gum solution, the boron ions help to bind the long polymer molecules together so that they do not move and flow easily.
When the polymer molecules come into contact with each other in the right way, the gum solution changes from being too bad to a rubber substance that we call mud!
What can you try?
Water is an important element in the mud. Water helps the polymer molecules pass each other until the mud flows. If you let the water evaporate, your mud will end up like a piece of solid plastic.
Try to make other samples of mud in different amounts of water and compare them with the first piece of mud. In each sample, follow the instructions to make the mud you followed before, but change the amount of water you add to make the glue solution.
Do not add water to the glue. Use only one tablespoon of glue to make the glue solution.
Add two tablespoons of water to 1 tbsp of glue to make glue solution.
You can choose to give each sample a different color mud to help you distinguish them.
