We’re back with a hot new episode on staying cool! We’re talking about the history of air conditioning, our favorite frosty invention. Joy and co-host Maeve meet a sassy talking ice unicorn who is trying to find a place to chill out (and not melt!). Find out what chocolate, chewing gum and macaroni have to do with the invention of air conditioning. Plus, hear about some eco-friendly ways to beat the heat (splash pads, anyone?).

First Things First is back, too! Find out which was invented first: frozen yogurt, slushies or snow cones. Find all this frozen goodness, and a peek into why school buses are yellow, in this episode of Forever Ago!
