I attempted this record back in 2019 and thought I surpassed the existing record of 16 balloons burst in the armpits with a run of 25 in one minute but I had too many disqualified because my hand was either touching the balloon as it broke or the balloons slit out of my armpit before breaking.

This time I found the solution: hang upside down. It still took multiple attempts and was nowhere near as easy as expected but I broke the record by breaking 26 balloons in my armpits in one minute. I took screenshots of every balloon in my armpit just before it broke with my other hand removed to be sure I get it this time.

The other trick to this record is that the balloons had to be bigger than the standard water balloons sold in stores so I needed to find some slightly larger water balloons to use.
