Kool-Aid stands were big in my neighborhood (upstate New York in the 60’s). But one day my friend and I tried a new angle… We got a hold of a refrigerator box, which we placed upright and decorated (with crayons? markers?) as a “Kool-Aid Machine”, just like a Coke vending machine. We cut a hole for the customers to insert their coins, and an opening from which the Kool-Aid could be dispensed. Then we got inside the box and waited for our customers. When they inserted their coins, we would pour the Kool-Aid (from inside the box), and a little hand emerged from the opening with a glass of Kool-Aid. What a “blast” we had!
