Mini sizing

Kr'rt, the lippy tentacle head, spake thusly:

And what if you are using those thrice-damned Agents of Gaming B5
minis that are hollow and can not be made watertight? How do we account for
water retention WITHIN the mini? Also, what if the hollow mini retains AIR and
adds a buoyancy factor to this procedure.

We need answers!
