On a swelteringly hot day Kevin and Alanna find Uncle Norm covered in perspiration...and, is that yogurt all over his face? He picked up frozen yogurt cones for himself and the kids, but they immediately started melting, so he had to, well, ya know, eat them. To show Uncle Norm how cool it is to know about different temperatures Alanna makes a hands-on visit to a master glass blower, who treats us to a wide variety of hot and cold issues she deals with everyday.
