Gooey Mess!

This morning all the Year 5's from Room 6 came to Room 14 to do a gooey science experiment. First we put newspaper down on the floor. Then we got a board and put it on the paper. Next we got a bowl and put two cups of cornflour in the bowl. After that we got a cup of water and mixed it in. Mrs McAvoy came around with green food colouring. We mixed it all up. We created....well we really don't know what we created. It was like a liquid, it moved around and dripped out of our hands. But when we punched it, it was solid. How strange! All we do know is that is was a lot of fun and very messy.

Here is the recipe if you want to make some at home.

2 cups of cornflour
1 cup of water
A few drops of food colouring

Put all the ingredients into a bowl. Mix it together slowly and then you are done. When you have finished experimenting wash your hands etc in a bucket of warm soapy water and then tip the water on the grass. The gooey mixture will block your drain. Any mess of tables can just be wiped up. If you spill some on the floor, it's okay wait for it to dry, and it vacuums right up. Amazing stuff!

Try some of the things we did...
Touch it
Squeeze it
How does it feel?
Put your fingers slowly into it, what happens?
Now punch it hard, what happens?
