Mythbusters tried it, and concluded that there was no significant
sucking sown.

I have often the impression their experiments are designed
in the first place rather for the effect,
than to really investigate the nature of phenomena.

E.g. I watched their investigation of economic effect
of frequent switching on/off
the incandescent, fluorescent and LED lights.

They were over focused to refute the obvious nonsense
the light at switching consume more power
than saved by being off, and were successful there.

OTOH, experiment part about saving power
versus shortening device life was very poorly designed
and result had no statistical value.
