Above is a picture of the Kool-Aid packets that many of us grew up with. Just add water and (more) sugar! The packets seem to be Kool-Aid's signature product.
In class we briefly discussed the creation of a Kool-Aid Capri-Sun-type drink; looks like they already thought of that with Kool-Aid Jammers.
Kool Pops - The Kool-Aid flavored version of the ever popular Otter-Pop. I don't know of anyone who doesn't like Otter-Pops, nor do I know of anyone who buys Kool Pops. Perhaps Kool-Aid extended its name to a product that is already dominated by another brand.
Something we didn't consider was Kool-Aid clothing. Clever, but given the brand's decreasing popularity, the creation probably came too late. By the way, the shoes have the brand logo on the back and have "Kool" imprinted on the soles... there's no way to hide the fact you're wearing Kool-Aid shoes.
