In Science in Year 4, as part of their learning about solids, liquids and gases, the children have been investigating materials which can be more difficult to categorise . They explored oobleck, a fascinating non-Newtonian fluid, which behaves like a liquid when ‘unstressed’ and can be poured but acts more like a solid when force is applied .

They also learnt about other examples of non-Newtonian fluids, and were amazed to discover that it would even be possible to walk across a swimming pool filled with custard without sinking!
