The secret of the slime source factory is revealed: everything you play comes from here!
Knowing these, you can also make Slime
Slime, this sticky, soft but highly plastic substance, is not only loved by children, but also aroused great interest among adults. It can be used as a decompression toy or as an interesting handmade material. So, how is slime made? Today, let’s take a deep look at the source factory of slime and how to make this magical substance at home.
Before talking about the production of slime, it is very helpful to understand some basic scientific principles. The production of slime depends on a substance called “polymer”. Polymers are long chains of molecules composed of repeated connections of the same or different simple molecules. Common polymers such as sugars, proteins, and plastics are everywhere in our daily lives. The polymers needed to make slime are formed into a network structure by adding cross-linking agents, so that they have a unique viscoelastic appearance.
Basic recipe and production steps
Material preparation:
1. White glue or PVA glue
2. Water
3. Borax solution or contact lens solution
4. Food coloring (optional)
5. Glitter, beads and other decorations (optional)
Steps:
1. Mix glue and water: In a container, mix white glue with an appropriate amount of water and stir evenly. The proportion of water can be adjusted according to personal preference. If you want the slime to be softer, you can add more water.
2. Color and color: Add a few drops of food coloring and stir evenly. You can make slime of different colors according to your preferences.
3. Add borax solution: Add a small amount of borax solution or contact lens solution to the mixture little by little and stir slowly. It should be noted here that the amount of addition must be done gradually, because too much borax will make the slime too hard. As the cross-linking reaction proceeds, you will find that the mixture gradually thickens and eventually forms a slime with unique viscoelasticity.
