Why zero gravity is important
Foam is unstable in gravity because the liquid between the bubbles flows downwards.
When the liquid film between the bubbles is very thin, it can break and the foam collapses. Foam is easier to study under zero gravity conditions because weightlessness causes bubbles to be evenly dispersed rather than floating to the top.
Nestl has been followingESAs activities in this field for over a decade. This is the first time Nestl is conducting foam experiment
