- School kids - First Guess: 17 Second Guess: 2
- Postgraduate students - First Guess: 18 Second Guess: 10
- OR 54 Delegates - First Guess: 23 Second Guess: 3

The above is just 1 example of an outreach event that works really well in schools (and also with more "mature" participants). If you do want more examples please do take a look at http://learnaboutor.com/.
