André Kuipers shows that foams are affected by gravity

As part of the PromISSe mission, André Kuipers undertook an extensive education programme called Spaceship Earth.
This involved performing two experiments which demonstrate the effect of gravity of everyday phenomena such as convection and formation and collapse of foam.
In this short clip, André performs the experiment in space and concludes that in the absence of noticeable gravity, fractions do not separate as they do in space, air, foam and liquid phases are not distinguishable.
Interestingly, the foams last much longer in space than they do on Earth as bubbles are not subjected to the gravitational forces that lead to the draining, coarsening and eventual collapse of the foam.
