OK, I do have a suggestion here...
The device has an electronic switch, which, with a little care could be replaced with a magnetically activated reed-switch.
Now, with this in mind, switching could be done quite remotely - meaning the bolt could be screwed inside a glass jar and sealed by the spectator.
Then, with a mysterious wave of the magi's "PK'd" hands - voila, the bolt operates.
Surely the sound against the glass of the jar will mask the nosies?
I can't comment really, as I don't have this effect - but for the sake of about 50p for a reed switch and a bit of soldering, this would surely kill three lemons with one aadvark???
