Science Experiment - Cornstarch

This is P's experiment to investigate the "cage" molecule structure of cornstarch.

First picture shows cornstarch powder mixed with water.

Second picture is P's fingers pinching a lump of cornstarch mixture. If you were to do it, the lump felt powdery like cornstarch in solid form.

Third picture shows a lump in solid form.

In terms of the explanation. The cornstarch has a "cage-like" molecule structure. So when one squeezes the cornstarch solution, the water molecules get squeezed in the cage. The resultant molecules line-up is similar to that of solid.
