I can envision this and with trading lessons for GCEI one gets thirsty. I'll throw in a lemonade stand that is mandatory to use so that a few will learn a lesson in economics and capitalism. I think 2 dollars a glass for starters will be about right. Lemons, water and a teaspoon of sugar doesn't come cheap! And we will be generous. Baby cups they will have to provide. Don't want spillage!
