medical health first aidWhy does cornstarch and water turn into a solid?
The cornstarch and water mixture acts like asolid sometimes and a liquid at other times. Thisconcoction is an example of a suspension (a mixture of twosubstances), one of which is finely divided and dispersed in theother. When you slap the cornstarch quicksand, you force thelong starch molecules closer together.
Similarly, it is asked, what happens when you mix cornstarch and water?
The Oobleck mixture isn't your typical liquid—orsolid. The cornstarch-and-water mixture creates a fluid thatacts more like quicksand than water: applying force(squeezing or tapping it) causes it to become thicker.
In this way, how do you make cornstarch liquid solid?
Add water slowly, mixing the cornstarch and waterwith your fingers until all the powder is wet. Keep adding wateruntil the Ooze feels like a liquid when you're mixing itslowly. Then try tapping on the surface with your finger or aspoon. When Ooze is just right, it won't splash--it will feelsolid.
Cornstarch, the main ingredient of Goop orOobleck is made up of long chains of atoms. When you movethem slowly past one another, they flow like a liquidbecause they can slide easily past each other. When you squeeze,roll, or agitate them, the “atom chains” will getentangled and form a solid!
