Several weeks ago we had an office discussion that eventually got around to xkcd and the fascination with ball pits, to pranks involving filling up a cubicle with balls or packing peanuts. The problem with such pranks, it was observed, is that balls are expensive and balls or peanuts take up the same volume ahead of time — storage is an issue. But balloons … they don’t suffer from this problem. You could fill a colleague’s office with balloons.
“That would be cool,” that colleague was heard to utter.
To me, such a statement is an invitation. It would be rude to not fill that person’s office with balloons, should such an opportunity arise, and I fear that someone might do it. So it got me thinking. How would one go about doing such a thing? (Not that I would do such a dastardly thing — I wouldn’t want to expose myself to a wrongful breath suit)
First thing would be to obtain a pump. Double-action, so it fills on both the up- and down-stroke.

When filling the balloons, I would use a balloon clip to speed things up (tying is such a pain) and would find that twisting the neck is important, otherwise the air would tend to quickly leak out.

Then, I would start filling the office. Maybe during lunch hour, or at odd times during the day (and staying late to ensure my real work was done). Get an idea of how many balloons I and any co-conspirators could fill. The progress after one day might look something like this

After four days, it might look something like this

I’ll bet with some help I could use up 200 12″ balloons and 122 (50+72) 17″ balloons, along with a few balloon-animal style balloons (which would be close to useless, since they take up so little volume). With that many, I’d probably notice that there is significant balloon-stink. And I would find the non-stick agent they use (probably cornstarch) to be really annoying after a while.
To be especially devious I might even fill some of the balloons with confetti, so that popping them all would become more of a challenge. I might be tempted to also fill some with helium, but they wouldn’t survive the weekend, so I wouldn’t bother. I’d probably find that about 10% of the balloons would be lost to defect and breakage, and would be amused by the occasional “boom” coming from the office. I’ll bet it would remind me of the episode of the Simpsons where Homer becomes the Beer Baron (Homer vs. the 18th Amendment), and his stills kept blowing up.
If I were to do such a thing.
