In Science we made goo. We wanted to see if a liquid could be a solid at the same time. We found out that it can because of its viscosity. High viscosity means something is all sticky and has trouble moving. Low viscosity means it is really easy to move like petrol, water and milk. Examples of high viscosity liquids are caramel and cold honey. Our icky goo was awesome because it was a solid and liquid at the same time and had high viscosity and low viscosity at the same time. We made a mess!
