Trade Show Treasure Hunt

I saw this idea at GreenBuild. A large, flat screen TV in the Hycrete booth, showing a company video, had a sign saying, "Win this TV." But instead of the usual "deposit your card here" type of drawing, applicants had to answer questions based on information displayed in the booth.

Here is the entry form:

The back of the form had a map showing where to find the answers in the booth:

The quiz would have been more effective as an educational tool if the answers were information the attendee could have used (instead of generic "Option A/B). But still, this is a good idea that got attendees to spend more time in the booth and give it critical attention instead of just a walk-by.
