Foam result surprises scientists (Oct 25)
http://physicsweb.org/article/news/9/10/14
The flow of air over the wings of an aeroplane provides the lift that
keeps it in the air. However, physicists in France have discovered that
when a foam flows over an aerofoil, the resulting force is exerted
downwards rather than upwards. The force - which the team calls
anti-inertial lift - work could have implications in fields as diverse
as oil extraction and industrial cleaning processes (Phys. Rev. Lett.
95 168303).

And would have implications on any planet which has a foam atmosphere;
airplanes would never get off the ground!
It could happen!!!!!

E.T., foam home...

The video is garbage and looks like it is upside down.
However, if you invert it, it appears the "airfoil" has a negative
angle of attack.
If it does, it will also have negative lift because of the angel of
attack.
I'm unimpressed.

foam pumps dont pump backwards.
Have the dumbasses go get a foam pump.

put a prop in foam and let me see you back up

You cold probably build perpetual motion machine in a washtub.
I tried to jam an airfoil though a piece of styrofoam to confirm the results
of that research and all I got was EPS beads all over the place.

As Al Queda places an order for 6.02*10^23 liters of liquid detergent, the
FBI places Palmolive on a list of watched chemicals.

This could be the end of rubber ducks as we know them. A whole new
generation of bubble bath toys is imminent.
