Arielle is curious about some big, long, squiggly, textured balloons she found. With considerable effort, she blows one up, measuring the pressure as she goes, then deflates it, and reinflates it. The pressure requirement for the second inflation is considerably less, as she predicted. She then tries another by pre-stretching it, then blowing it to full length. As predicted, that required slightly less pressure than the first inflation, but much more than the re-inflation.
