Why not have a go at making oobleck!!!  What is oobleck I hear you cry?  It is simply a mixture of cornflour and water. 

You will need 1kg of cornflour, water (added until the consistency is wet, but solid when squeezed), food colouring (Optional), ice cubes trays (optional),  a mixing bowl, colander, funnel and beakers (again optional, but great for messy fun!).

 

How does Ooleck work?   Cornflour oobleck is made up of molecules arranged in long chains.  When the chains are stretched the liquid will flow, but when you force them together they stick to form a solid.    You don't have to use 1kg you can use however much you want.  Just add water slowly until the consistency is wet, but solid when squeezed. 

 

Now have some fun!  It's great for practising writing your letters and numbers in.  Have a go a pouring it through colanders and funnels. 

 

FUN FOR ALL AGES!  Yes mum, dad and anyone in the house can join in the messy fun too!
