In chemistry class with a mix of brilliant mixtures I made Play-Dough!!! Here the trick:
- First of all put a solution on the a hot plate.
- Put the flour down on it.
- Heat this flour and mix it by stirring this flour.
- Drop in some food coloring to add an effect for color.
- Keep Mixing until dough is ready and heated.
- Turn of the burners and let it set. Soon you will have Play-Dough!!!
Science: The chemicals mixed form a
compound the compound is essentially a starch-based binder mixed with water, salt, lubricant and preservative. To be more specific, it contains:- Water
- Starch-based binder
- Retrogradation inhibitor
- Salt
- Lubricant
- Surfactant
- Preservative
- Hardener
- Humectant
- Fragrance
- Color
Each of these ingredients has an effect on the compound's texture, fragrance and appearance. One of the major contributors to the softness and texture of Play-Doh compound is the interaction between its two primary ingredients - starch-based binder and water. To understand how the dough works, you have to know a little about starch and what happens when it comes into contact with water.Starches are polysaccharides, or strings of sugar molecules.
