But on the other, most viral puzzles or riddles tend to be really f*cking tricky and usually result in me starting at my computer screen for minutes on end as I stubbornly attempt to solve them without looking at the answer.

But alas, my brain teaser obsession is still going strong (along with my ever-growing forehead wrinkles), which is why I'm here to present all other puzzle fanatics with a challenge that'll really get you thinking.

I unfortunately didn't figure it out on my own and needed the trusty solution video below to clue me in. Can you figure this one out without taking a look at the answer?
