Hey Kool-Aid!
Kool-Aid was invented by Edwin Perkins in 1920. Kool-Aid was originally called "Fruit Smack." It was a Jell-O like substance that came in six flavors in a glass bottle. But the bottles were hard to ship and they broke a lot. So then in 1927, Perkins made the substance into a powder and put the powder into envelopes and they sold for ten cents a packet. The six original flavors were strawberry, cherry, lemon-lime, grape, orange, and raspberry.
