How To Cut A Watermelon With Dental Floss!! *TOP 5 BAR TRICK BETS YOU WILL ALWAYS WIN*
Five bar bets, one dental floss trick, and a watermelon that gets sliced without ever touching a knife.
Sean, the YouTuber behind the channel ItsYeBoi, dropped another entry in his long-running “Brain Games” series on August 5, 2019, and this one leans on a title too good to scroll past: cutting a watermelon clean with dental floss. The video, “How To Cut A Watermelon With Dental Floss!! *TOP 5 BAR TRICK BETS YOU WILL ALWAYS WIN*,” pits Sean against Team ALBOE regulars Ryan Swaze, ChadWithaJ, and DrHobs (known to the channel as Ghee) across five separate puzzles, with the floss-and-watermelon stunt saved for last.
The format is familiar to anyone who’s watched the channel’s earlier “cut a potato with a straw” or “slice a lime with a cigarette” episodes: quick-hit challenges, a little trash talk, and a payoff trick that actually works if you know the mechanics behind it.
- The episode runs through five distinct bar bets rather than five versions of the same fruit trick, ending with the dental-floss watermelon cut as the title challenge.
- Contestants include Ryan Swaze, ChadWithaJ, and DrHobs (Ghee), all regulars from Sean’s Team ALBOE crew.
- The watermelon solution requires wrapping floss around both hands, pushing it straight down through the flesh to cut wedges, then sliding it horizontally along the rind to pop the slices free without a knife.
The Coin and Line Puzzle That Opens the Episode
Sean kicks things off with a classic misdirection puzzle: place three coins across a drawn line so that two heads land on one side and two tails land on the other. It sounds like a math problem until you realize the trick isn’t in the counting — it’s in how you place the coins. The solve involves setting one coin directly on top of the line, standing upright or straddling it, so it effectively counts toward both sides at once. Watching Ryan Swaze and ChadWithaJ talk their way through the logic before getting stumped is half the fun of this kind of stunt content, the same DNA that runs through channels doing oversized challenge videos built around a single gimmick that only makes sense once you see the trick executed.
Rolled Bills, Pens, and the Coca-Cola Bet
From there the episode moves into a string of disentanglement puzzles — banknotes rolled and looped around pens, coins that need to be freed or repositioned without touching them directly. These are the kind of bets that live forever in dive bars precisely because they look impossible on first glance and take about ten seconds once someone shows you the move.
The fourth bet swaps sleight-of-hand for physics: a shaken can of Coca-Cola that has to be opened, or have its pressure released, without spraying soda everywhere. It’s a staple of the bar-trick genre for a reason — everyone’s seen a shaken can explode, and everyone assumes there’s no way around it. Sean uses it as a bridge between the manual dexterity puzzles and the knife-free fruit-cutting stunt that closes the video out.
Wrap the floss around both hands, push it straight down through the melon, then glide it flat along the rind — no knife, no mess, slices pop right out.
The Watermelon Cut That Gives the Video Its Title
The main event is exactly what the title promises. Sean hands a contestant a pre-cut wedge of watermelon and a strand of dental floss and tells them to separate the fruit from the rind completely — no knife allowed. The technique depends on tension: wrap the floss tight around both hands so it acts like a taut wire, push it down vertically through the flesh to score individual wedges, then run the string horizontally along the bottom of the rind. Done right, the slices pop free in seconds, looking like they were portioned by a chef rather than sawed off with string.
It’s the same principle behind cutting soft cheese or cake with floss — a thin, tight line concentrates force enough to slice through soft material cleanly, without the crushing and tearing a dull knife edge causes. Applied to watermelon, it means no rind fragments in the fruit and no sticky knife to wash afterward, which is exactly the kind of low-effort payoff that makes this content shareable in the first place, not unlike the stunt-driven appeal of a video like the escape room challenge format that hinges on one clever solution landing at the right moment.
Whoever loses each round in these ItsYeBoi episodes usually ends up on the hook for something — cash, a dare, or just bragging rights lost to Ryan Swaze or ChadWithaJ for the rest of the week. The floss trick itself, though, needs no losers: grab a strand, wrap your hands, and the watermelon does the rest.
