A few brief stories--
I've had LEGO displays in fish tanks for the little fishes to swim through.
After years of staying in the fish tank, I found that the LEGO pieces were stuck
together quite firmly, and some pieces took much effort to pry apart.
I filed that away for no real reason.
I bought a house last August and promptly set up a LEGO train layout in the
basement. Then spring and summer arrived with much rain and humidity, and I
noticed that many of my large blue baseplates sitting on the wooden train
modules were getting all warped, and that my 9 volt train wheels were really
starting to bind. Dragging out the dehumidifier last week and leaving it on for
a few days (and subsequently dumping lots of collected water down the drain),
I've noticed that the blue baseplates are gradually flattening out, and the 9
volt wheels are not binding as bad as they once were.
So a few things--
There must be different 'grades' of plastic (ABS, whatever) that LEGO bricks are
made from--Every blue baseplate warped--none of the green or grey ones warped.
I thought that this fact alone was rather odd.
The tolerances on 9v wheelsets must be quite small for the humidity to affect
them that much.
I didn't think that LEGO bricks could 'absorb' water moisture. Always had it in
my mind that ABS was 'waterproof'. Eh, live and learn.
