If there’s is no weight (no gravitational force) then the only force acting on the liquid is surface tension.

Explanation:

In this case surface tension will pull the liquid upwards to fill it. Normally this process stops when the upwards force of surface tension balances weight ... in the absence of weight it will continue.
