I like the challenge, but perhaps you could twist it a bit...
Challenge: Make a block that falls off when a visitor touches it...and see how long it takes for them to mention it, if they ever do. Perhaps the falling block could activate a timer. When they mention their 'ooops' moment you put the block back, read off the timer by lifting off the roof of a little shed, and announce, "Hmmm...2 minutes...a new record!"
hock: 
The real challenge would be setting it up so that it entices them to want to touch the block, and that it will be so lightly held in place that it automatically falls off with the slightest touch. Heh heh heh.

I may not be a rivet counter, but I sure do like rivets!
