What makes all liquids the same? What makes liquids different from solids? Liquids flow and take the shape of the container. Liquids flow and change shape, solids do not change shape unless they are made to.

This is causing us problems. It makes a very thick liquid that does not flow easily through our pipes. It is also very hard to stir, and we need a lot of electricity to run our stirring machines. This is very expensive! Dear Scientists, Glues 4U produces special glues for chocolate makers. They use them for sticking their wrappers together. We have found that the best starting ingredient for the glue is a liquid that we get from trees. We would be pleased if you could help us to solve our problem by testing the viscosity (thickness) of different sorts of liquids. Can you suggest how to make our liquid flow more easily? Is there a different liquid that we should use for our glue? We look forward to hearing from you, by phone or , soon. Jane Wellington (Operations Manager)
