Cornflour Slime  Oobleck!

We discovered oobleck  has properties like a liquid. It can pour off a spoon and flow through our fingers. It also has properties like a solid when you hit it with a force it holds its shape. If you try to quickly push your finger in it it feels like a solid but if you slowly push your finger through it flows like a liquid.  

We found 2 cups of cornflour to one water made the best ooblek.



Making Bath Bombs - We made careful observations to identify the mystery substance - It was citric acid ! It tastes sour and is used to make sherbet.
