Solid or liquid?

We have over a period worked extensively laboratory and we talked about the substance in different physical state. As a fun end I showed the class a little experiment.

Mix corn starch or potato starch in some water and try to figure out if it is in solid or liquid form.

The children became very enthusiastic and appreciated the experiment. I think many of them also have shown their new "party trick" at home.
