Corn Starch Reflection


Is the corn starch a liquid or solid? Well, when you see it you are sure it is a liquid, but once you touch it, it is a solid. When you touch that mixture you feel it dropping but if somebody touches the corn starch it is going to be hard. If you put pressure to it (move it very quickly) it did looked like it was clay ball, but once there was no pressure it was again a ‘sliquid’ (solid+ liquid). When your hand were in it I felt a liquid on my hand and that’s true because it is a ‘sliquid’. But when it dried it became like a wax around your hands. It was very COOL!!
When there was too much water it was very liquid just like water but it still had a little bit of that hard sensation. When there wasn’ t enough water it was as hard as rock and you couldn’ t pick it up. It was very, very hard. And in this way it looked more like a solid. But when there was the right amount of water  it felt a very COOL sensation.
I don’ t think the corn starch changed a lot. Though after some time you    don’ t touch or play with it it becomes harder and harder.
My hands were surrounded with a strange type of wax. Once I washed my hands, my fingers were like the witch, with sores over them.
I am not sure if this mixture is a solid or liquid, but I think it depends on how much water you put. This messy and fun experiments are the best ones!!
