This is a video to show you what corn starch can do.
When i made oobleck what happened was when i held it in my hands and was doing something to it it stayed and the second I relaxed it became a complete liquid and flew down. Also when i pounded it, it w2as a solid and when i dipped my hand in it, it was a liquid.When we did this is class me and my partner put to much water in the corn starch. The corn starch made it softer and more liquid like than all the other ones. Then we took some water out and it became harder. In the end we were pretty successful. Now it is drying and becoming corn starch again!
