That's my experience as well.  I tried to put water into my pneumatics
gear as a child, but it never functioned again after that.  Perhaps it
would have worked if I'd let it dry more thorough?  I'll never know, but
in the mean time I'll concur with James Pritchard below:

I advise everyone to keep air and NOT water in there pneumatics.

Then again it's been along time since then LEGO may have improved the

Perhaps, but the pneumatics is basically the same now as in the JCB

now ruined due to exposure to water.

I've always found the 8250 Sub to be a bit "offensive" in this way: Does
it not ask to be put into water, having the shape of a sub marine?

Shortly after that the seal on the inside failed and they became useless. I advise (...) (25 years ago, 11-Aug-99, to lugnet.robotics)
