This guy is apparently some annoying science YouTuber who likes to record himself breaking obscure Guinness World Records. While his achievement isn't meaningful, it's still pretty funny to watch him squirm through the pain of pure lemon juice.

In just under 17 seconds, this man vigorously sucks down one liter of lemon juice, then seems to go into shock for a few seconds from the enormous amount of citric acid.

Considering this man tries to teach kids about STEM subjects, it's unclear what we're supposed to learn from watching him succeed at this inane goal.

Maybe he just put it out there as a reminder of what NOT to do?
