On Tuesday the 13th of March Ngaumu class went to the Science Road Show at Channel College and I volunteered to have oeblek goo poured on my head. None of it went on my head because when you add force to it it becomes a solid but you if pick it up its drippy like liquid. This is called a physical change
Oeblek goo is so easy to make. All you have to do is put corn flour into a bowl with water and some food colouring. Mix it around and enjoy playing with it.
