- Yes, Iknow exactly how it works. When you try to move it quickly, the
- water molecules move away from the starch, and the starch molecules are
- left to for a solid. When the water flow back, disolving the starch again,
- turning it into what you could call a liquid. It is fun stuff though.
- Yes, Iknow I used disolved loosly.
