OT: Floating across a river using helium balloons?

Err... Why not just cut/undo strings ?

They just Boyle away I suspect.

"The Large Hadron Collider near Geneva will be shut off until spring

2009 while engineers probe a magnet failure.

"The incident on 19 September caused a tonne of liquid helium to leak out into the experiment's 27km-long tunnel."

That would fill quite a few party balloons. Probably enough for one for every kid on the planet. I don't think scientists are in the position to complain about wasted helium.

Of course! That's the law.
