[Darkroom] pcb etching tank lid missing

[Jake]

so you may have noticed the ciruitboard etching tank which has been 
installed in the darkroom (on your left as you walk in)

i made a nice plastic lid for the etch tank, with little magnets to hold 
it in place.  It's gone!  and there's dust in the juice now.

The lid looks like a part of a take-out food container, cut to a 
half-circle shape, and with little magnets hot-glued to the corners.

I would really like the lid to be found and put back onto the tank, so i 
don't have to make another one.  You know how it is when you want your 
special chemical to be covered so it doesn't get all gross.

let me know if you have any ideas where the lid went, or if you want to 
make another one.

thank you
