RE: Flexible Numeric Keypad

I didn't intend to imply that you would stick your electronics in water. You
would mold the plastic, then _take out the electronics_, and dip the plastic
in water. You could then sandwich the internals between two (or more if
necessary) plastic layers and attach the two with adhesive or screws.
However, this may be too difficult for you, so you may wish to stick with
the latex.

I don't think so Mel,  "...dip in cold water to set.."  does not sound like
a great idea for electronics.
Nice try though. :-)
