Play Flour




With a mix of brilliant mixtures I made Play-Dough.




Heres the trick:
1.First of all put a solution on the a hot plate.
2.Put the flour down on it.
3.Heat this flour and mix it by stirring this flour.
4.Drop in some food coloring to add an effect for color.
5.Keep Mixing until dough is ready and heated.
6.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:


1.Water
2.Starch-based binder
3.Retrogradation inhibitor
4.Salt
5.Lubricant
6.Surfactant
7.Preservative
8.Hardener
9.Humectant
10Fragrance
11.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.
