Gablinger's Beer. It was low calorie, but I don't believe it was non-alcohol. It tasted like beer-flavored soda. There was no fitness craze going on at the time, so no one cared.

Hoppin' Gator Beer - the guy who invented Gatorade sold the product to someone else and with the money he made, tried combining Gatorade with beer. Can't imagine why it failed.

Hereford's Cows - something like Baileys Irish Cream, but in flavors - chocolate, vanilla, strawberry, and (heaven help me) root beer.

I had Fizzies once, not bad, but then kids will eat or drink anything. They died out because they were made with the now banned sweetener Cyclamate. Other artifical sweeteners (and sugar) won't hold together in tablet form.

Kelloggs cereal with dehydrated strawberrys and bananas. The fruit had the same feeling as papier mache. By the time the fruit became rehydrated, the cereal was completely soggy.
