You are watching: How to make someone pee in their sleep with water
Our middle School Mysteries series investigates childhood rumors you never bothered come fact-check yourself.
I have actually a restricted tolerance for continuing to be awake — as a son I was constantly the very first to loss asleep at slumber parties. Everyone knows the an initial person out is the an initial to obtain pranked. Ago then, among the most well-known pranks was dipping a sleeping person’s hand in warm water to see if they will do wet the bed, setting them up for a life time of urine-related nicknames.
I managed to do it through middle school without ever before getting pee pranked (let’s take it a quick moment that silence for those who were less fortunate). But I’m curious to recognize if dipping someone’s hand in warm water really reasons them to lose manage of their bladder.
If girlfriend look the pee test up on YouTube — and I extremely recommend girlfriend do — you’ll check out the results are inconclusive: periodically the check works, but much more often, it doesn’t.
But in 2009, the TV show “MythBusters” placed the whole matter to bed, so to speak. The show brought two test topics to a California sleep lab, hooked them increase to brain monitoring equipment and lined the bed through moisture-activated voice alarms. As soon as the volunteer got to deep sleep, the various other volunteer snuck right into the room and also dipped the sleeper’s hand in a key of warm water. Later, castle swapped places so the sleeper came to be the dipper and vice versa.
Neither volunteer wet the bed. But that doesn’t median it’s impossible.
The power of suggestion
According to a 1996 Gallup poll, 25% of every Americans identify as superstitious. This way that one 4 minutes 1 of the nation believes they can achieve great fortune by carrying a rabbit’s foot or by staying clear of ladders and black cats.
Psychologists believe our expectation are an effective enough to influence the result of a certain occurrence. Because that example, if you understand parties make you feel anxious and also drinking wine provides you feel much less inhibited, after drinking a glass you might find yourself feeling and also behaving in a an ext outgoing manner. The wine didn’t make you much more extroverted — but your mind believes it did.
The exact same theory holds true for the hand-in-water prank. Mental Floss posits that there’s one unconditioned solution between listening the sound of to run water and having come pee. Lock argue the dipping a hand in water might cause the mind to do a similar connection, thereby relaxing the bladder.
Mental Floss likewise suggests that “immersion diuresis” can be come blame for this phenomena. Immersion diuresis is once the human body is covered in water and subjected to transforms in pressure and temperature, causing urination. Because that immersion diuresis come work, however, the whole body would must be submerged, so mental Floss doesn’t provide this theory too lot credence.

Both MythBusters and Mental Floss compete that not sufficient research has actually been perform to do a definitive judgment on even if it is or not the pee check works. For this reason there’s only one thing to it is in done: Everyone step up and pee check a friend (or enemy) today.
