No. While the funnel is made visible by condensation, it is mostly air.

A tornado on water is called a waterspout. You will find a spray of water where the vortex reaches the surface.
tornado clouds
The funnel of a tornado consists of water droplets which condese as a result of a temperature drop inside the tornado that results from the low pressure. Temperature decreases with increasing heght, alowing more water vapor to condense.
A tornado that does not touch the ground is a funnel cloud.
A funnel cloud is like a tornado only it does not reach the ground.
A funnel cloud is a developing tornado that has not reached the ground.
The tornado itself is a whirling circular mass of air. Condensation of water droplets at the tornado's core forms the funnel.
