[TL39]

I've done it quite a fair bit, but that was because I used to work in events management way back when I was still a student. The company I worked for would help with event setup and clearing up, the latter of which involved popping any balloons that were left after everything was done.

We had a few tools for clearing balloons. Obvious ones were things like scissors, but we also had this box thing with open ends on both sides, 1 of which can pointed corners that folded inward. The general idea was that u would take a sting of connected balloons, like those u can find in arches or columns, and then basically pull them through the box, popping them very quickly. Saved a lot of time and effort.
