You closed the other thread before I had a chance to post this... 
I've seen other ones where people have had to guess the # of quarters or sample bottles in a jar... but since you are a juice supplier, how about having a contest where they have to guess the # of DROPS in a bottle??
You could pick whatever size of bottle and count out a certain # drops, post a close-up of it, and the person who comes closest to the actual # (without going over) would win...
It would be hard for people to duplicate at home, because the size of drops can vary so much!!
Anyway, just thought I would toss this out there
(and I don't think it has been done before...)
