In the old days when you ran a lemonade stand it was hard to keep the lemonade cold. The ice was a good idea however it would melt and cause the lemonade to become watery. Watery lemonade doesn’t taste very good. Now days you can purchase a generator that can power a tiny refrigerator that you can put the lemonade pitcher into to keep it cold. This removes the need for ice at all which keeps the lemonade tasting potent and fresh. The cold lemonade on a hot day was always a refreshing beverage to sell and people were glad to pay for it!
