Another solution for detecting tilt would be the kind of tilt device used in
old pinball machines (I don't know if it's still used). I'm not sure how to
explain it, but I can give you a similar example:
Hold a pencil at the end between your index finger and thumb, so the pencil
hangs down (and can swing a bit). Now take your other hand and make a
circle with your index finger and thumb. Hold this around the pencil near
the bottom. If your hands were connected together, you could detect when
they 'tilted' by detecting when the pencil touches your bottom hand.
If you turn the pencil into a metal rod, and your bottom hand into a metal
ring, and attach wires to both, you have a simple switch to detect tilt
(with some other hardware connecting the two).
This would eliminate the need to use some pesky toxic chemical, and should
be fairly easy to implement using mostly lego parts.
If you want, the pendulum could be replaced with one that moves on a single
plane and pushes a touch switch when it tilts (one switch for each direction
you want to detect)
I hope this makes sense.
