Alice has been tasked with comparing a series of Qualatex round balloons of different sizes, but the same color, to see how much pressure is required to start them, and subsequently, to burst them by overinflation. She began with the 5" size in a previous clip, and that took almost all the pressure she could develop. The 9 and 11-inch versions were considerably easier to blow but more dramatic when they failed from overpressure.

Alice has been tasked with comparing a series of Qualatex round balloons of different sizes, but the same color, to see how much pressure is required to start them, and subsequently, to burst them by overinflation. She began with the 5" size in a previous clip, and that took almost all the pressure she could develop. The 9 and 11-inch versions were considerably easier to blow but more dramatic when they failed from overpressure. The Q16 was a bit more of a challenge, while the subject of this clip, the Q24, gave her some pause due to its obvious much larger size and longer inflation time. For this one she elected to add a check valve, and proceeded to puff mightily until it was larger than her in every respect. She did pause midway to change to the tuba mouthpiece, since the green one was irritating her cheeks by digging into them at the corners, while the tuba one allowed her to puff with abandon.
