Styrofoam can be made by mixing crystal mud with materials that are easy to foam. For example, after mixing the crystal mud and shower gel, stir evenly, add water appropriately, and stir until it doesn't stick to your hands.

When making styrofoam, we must first understand the specific characteristics. General styrofoam is made of clay and glue. Without these two materials, you can use other foaming materials instead, such as mixed crystal mud and shower gel.

Crystal mud is usually sold in stationery stores or large supermarkets. Prepare enough crystal mud, a bowl that can be stirred, a wooden stick, shower gel and appropriate amount of water. First, add water to the shower gel and stir. When there are many bubbles, add crystal mud and keep stirring. If the foaming of shower gel is troublesome, you can use shaving cream instead. Add a proper amount of water and stir with a wooden stick until it is shaped and does not stick to your hands.

Pay attention to the safety and environmental protection of the selected materials when making styrofoam, especially when buying crystal mud. It is recommended to go to the supermarket and choose a regular manufacturer to buy it. Especially when children do it, they should be supervised by parents to prevent eating by mistake. Making crystal mud by yourself not only enriches your spare time, but also is safer and more environmentally friendly, and can also enhance your hands-on ability.
