Sahrye is preparing for some interesting and fun outdoor experiments with Zonah. They need to find out how much greater volume of air can fit inside a Qualatex 646 versus a 350. She has an apparatus that allows her to blow on a tuba mouthpiece to fill a Q350, then open a valve that connects it to a 646. The greater pressure in the 350 enables it to at least begin inflating the 646, but once the pressures equalize, she has to finish squeezing the air from the smaller balloon to the larger one.

Sahrye is preparing for some interesting and fun outdoor experiments with Zonah. They need to find out how much greater volume of air can fit inside a Qualatex 646 versus a 350. She has an apparatus that allows her to blow on a tuba mouthpiece to fill a Q350, then open a valve that connects it to a 646. The greater pressure in the 350 enables it to at least begin inflating the 646, but once the pressures equalize, she has to finish squeezing the air from the smaller balloon to the larger one. She then removes the used 350 and replaces it with a fresh one, because to re-use it would result in a larger volume and thus skew the results. Like so many experiements, the result is "it depends" - on how full you want the 646. While two 350's go most of the way toward filling the 646, it is able to stretch out (overinflate) to accommodate three 350's worth of air.
