Current will flow through the water. If the wires ar close
enough it will cause an overload. If they are far enough
apart they will heat the water and can make the water boil
between the wires.

This method has been used to load test DG's. 3 pointed
metal plates are fixed onto a triangle of wood and a phase
connected to each. When the plates are lowered into the
water current will flow through the water. The further the
plates are lowered the greater the current.

Note that this is very dangerous if great care is not taken
and all people are kept away from the water.
