It’s a solid… It’s a liquid… It’s Oobleck

As part of our project on solids, liquids and gases we have been learning about their properties and sorting lots of items into their correct categories, they are either a solid, a liquid or a gas … and then along comes Oobleck to confuse the situation.    Today in P3 we were making Oobleck which can behave like a solid and  a liquid without a change in temperature.

We tested it outside by putting some in a bag and adding a fresh egg, we then dropped it from a height to see if the Oobleck would make a solid around the egg and protect it from breaking.  We managed  a drop of 2.6 metres, the egg finally broke when thrown directly at a wall.   Very messy science but great fun!
