To determine whether something is a gas, a liquid or a solid, apply the following test: place the test substance (X) in a closed container (Y), which is larger than the substance (X). If (X) retains is shape and volume, it is a solid. If (X) retains its volume but assumes as much of the shape of (Y) as it can, then (X) is a liquid. If (X) retains neither its shape nor its volume and completely fills (Y), it is a gas.
All of which proves that water is air with holes in it.
