I went shopping a few days ago and bought a couple of enormous balloons! I want to see just how big I can get them before they explode and pop. I'm going to blow them until the rubber finally gives way under the pressure and pops. The packet said they were 18” but when I blow them up I'm sure they're at least two feet across. The noise they make when they finally pop is incredible and I almost make myself dizzy from the effort required to inflate them enough to achieve a pop.
