A simple course of making styrofoam at home

A simple tutorial for making styrofoam at home is as follows:

1. Pour half a cup of glue into a glass, and then add a small amount of pure glycerin.

2. Squeezing into shaving foam can add super wire drawing effect to styrofoam.

3. Stir the glue, glycerin and shaving foam in the cup with chopsticks until they are evenly mixed.

4. Add borax water several times, stir while adding it until it is molded, and then test the extensibility of bubble gum by hand after molding.

5. In the process of stirring, if you feel your hands are wet, you can add some glycerin at this time and continue stirring until you finally feel your hands are not wet. If you want other colors, you can add some pigments.

Introduction:

Styrofoam is an entertainment product with the characteristics of softness and foaming, but it is also an industrial product, which contains ethanol, borax and other ingredients and has slight toxicity. Long-term use will irritate the skin and its smell will irritate the respiratory system. It is recommended to use it as little as possible. The main usage is continuous kneading and stretching, so that the volume of styrofoam becomes larger, and more and more bubbles are produced, which is more and more fluffy. The sound of poking and scratching has the function of comfort and decompression.

The first fully synthetic foam rubber came from the Belgian Leo Hendrick-Baekeland, who registered the patent of phenolic plastics on July 4th, 2002 at/kloc-0. After studying abroad successfully, I went to the United States to engage in chemical research. Encouraged by Professor Columbia University, Baekeland stayed in the United States and worked for a photography supplier.
