More on the solvent..

[Jon Cato Lorentzen]

Again, more SPOILERS below...

The problem with the Universal Solvent pulling Scrooge could be solved like
this. Both the solvent and Scrooge has some mass. As both are in a space
with no gravitation, they would be drawn towards each other, so
Scrooge would be pulled downwards towards the fluid, while the solvent
would be pulled upwards towards Scrooge. This way Scrooge could do his
little jig around the fluid.

And I'll be going to the great north for my Easter vacation today, so 
see you all in some weeks, and have a nice holiday.
