Group 1 of the periodic table contains the alkali metals. They all have a low density and can float on water, they have low melting points and are very soft - you can cut them with a knife. They are however, extremely reactive.

The following video demonstrates the violent nature of the chemical reactions of the alkali series of metals with water.

A simple mixture of flour and water produces a a non-Newtonian fluid. This fluid has unusual properties. The greater the force that is applied to it the more rigid it becomes and the more it behaves like a solid. As the force is reduced on the fluid it becomes more liquid and runny.

This is an amazing video which demonstrates the unusual properties of a mixture of flour and water.
