Transcript of Properties of cornstarch
What is Cornstarch?
Cornstarch is made up from the endosperm of the kernel. Cornstarch is produced by grinding and washing the kernel until there is a fine white powder.
What happens when mixed in water?
When cornstarch is mixed in water, it produces a Non-Newtonian fluid. The mixture is actually a suspension and the cornstarch forms small strands. When pressure is applied the strands need time to move out of the way. If the pressure is pushing on the non-newtonian fluid and giving it not enough time, then the mixture gets hard.
Cornstarch only catches on fire when it is dispersed allowing oxygen to get in between each molecule of cornstarch.
