Oobleck

We made oobleck today. You make it by mixing cornflour and water until you get a paste. It's very weird because it does some things you don't usually expect a paste to do. This is what we observed:

• When you push on it fast, it's hard.
• When you push on it slowly, it's soft.
• It can drip off a spoon just like honey.
• You can form it into shapes like cubes and spheres.
• It goes crumbly if you keep rolling it between your hands.

We discovered that when you apply pressure to oobleck, it acts like a solid and when there is no pressure, it acts more like a liquid. We found it very interesting!

We finally finished our art activity from last week. We had painted two pieces of paper with brightly coloured circles. Then, we ruled lines on the back, cut them into strips and threaded them together. Don't they look amazing!?
