Drea Morgan tries out a Chinese hot water bottle, using our new handheld tube that provides a tap-off to record her blowing pressure. In a departure from past practice, we have chosen to record the pressure on Drea's side of the one-way valve. The very short tube and large expansion ratio of the hot water bottle make for a pretty extreme thrill for Drea. She has blown up some rather large balloons to bursting, but has never taken on anything as thick as a hot water bottle. But anyone who knows her is aware of her cool head and determination.
