When making foam rubber, it is usually necessary to mix these substances with some liquid rubber, water glycerin, foaming water and borax water, and then stir them. It usually takes 10 minutes to 20 minutes to make styrofoam.

Expand knowledge:

Two methods of making foamed polystyrene with kitchen materials. Prepare two kitchen materials, flour (wheat flour, corn starch, starch) and baking soda, glue and shampoo.

First, the production process

Pour the flour into the container first, and then pour enough shampoo. It is recommended to use expired shampoo to avoid waste, then stir until it is completely mixed, and even add some pigments to increase its color, and then continue stirring until the flour is completely dissolved and sticky. Add some liquid glue and baking soda and continue stirring until it becomes styrofoam.

Second, what should I do if styrofoam is too sticky?

According to the viscosity of the mud, a proper amount of baking soda can be added to the mud. Don't add too much at a time, add it several times. If you add too much, the mud will harden and it's not fun.

If you accidentally add too much, it will be too hard. You can keep it with a little toothpaste. If you still have contact lens care solution at home, you can mix it with molded water and saturated baking soda water and apply it while playing. The effect is also good!

Third, make styrofoam at home.

If we want to make styrofoam at home, we must first prepare a disposable cups and pour glue into it. After pouring out almost half a cup of glue, add glycerin and shower gel to the glue and mix well.

Then take out a proper amount of soda water, pour it into the mixed glue, glycerin and shower gel and stir it with chopsticks, so that the glue can slowly solidify and form, and then we can take it out to play.

The reason why we use shower gel when making styrofoam is because it can make styrofoam have better drawing effect and make styrofoam more interesting to play with.

Styrofoam also contains a certain amount of chemicals, so try not to touch it frequently at ordinary times, so as not to cause some impact on the skin, especially if the skin is delicate and may be accompanied by allergic symptoms.
