There is a popular belief that if you put someone's hand in water while they are sleeping, they will end up wetting the bed. This prank is often attempted on friends, especially at summer camps, and many people claim that it works. However, when tested in a controlled environment by MythBusters, the results were inconclusive, with no wet beds. The potential mechanism behind this phenomenon is suggested to be the power of suggestion, where the sound or image of running water can trigger a sense of urinary urgency. While the efficacy of this trick is disputed, it is believed that a combination of deep sleep and the power of suggestion might increase the chances of the prank working.

What You'll Learn
The myth has been busted by MythBusters
The myth that sleeping with your hands in water will make you wet the bed has been busted by MythBusters. The MythBusters team, consisting of Adam Savage, Jamie Hyneman, Grant Imahara, Kari Byron, and Tory Belleci, tackled this myth in one of their episodes. They enlisted the help of the California Center for Sleep Disorders and set up an experiment with moisture-sensitive alarms to test if the myth was true.
The experiment involved Adam and Jamie taking turns as test subjects, with the other person ready to place the sleeper's hand in the water once they achieved a deep sleep. However, the test did not go as planned due to Adam's sleep apnea interrupting his sleep, and Jamie was only able to pour water over Adam's hand, which woke him up. A third trial was conducted with crew member Matt Cordova, but the alarm was triggered due to water spilling out of the bowl rather than bed-wetting.
While the MythBusters team was unable to provide conclusive evidence due to the challenges faced during the experiment, they busted the myth by showing that simply placing someone's hand in water while they sleep is unlikely to make them wet the bed. The myth may have persisted due to the power of suggestion, as some people associate warm water with relaxation, which could influence urination. However, the experiment conducted by MythBusters did not find any evidence to support this claim.
It is important to note that while this myth has been busted by MythBusters, there may still be individual variations in how people respond to sleeping with their hands in water. The experiment conducted by MythBusters had a small sample size and faced interruptions, so further research with a larger sample size and controlled conditions could provide additional insights into this phenomenon.

It may work if the sleeper is drunk
The 'hand in warm water' trick is a well-known prank where someone sleeping with their hand in water will supposedly wet the bed. This phenomenon has been tested by MythBusters, who were unable to confirm the myth. However, there is plenty of anecdotal evidence suggesting that the prank works. Some sources suggest that the trick may work if the sleeper is drunk, as they might ignore the alarm signals from their body urging them to wake up and urinate.
The success of the prank is also thought to rely on the power of suggestion. The sound or image of running water can instill a sense of urinary urgency, and wet hands are associated with urination through the act of handwashing. Additionally, immersion in warm water is a common relaxation modality, and it is possible that the combination of a deep sleep and the relaxing effect of warm water could contribute to the success of the prank.
While there is some speculation that the trick may be more likely to work if the sleeper is drunk, there is limited experimental evidence to support this claim. The efficacy of the trick remains disputed, and it is important to note that the plural of anecdote is not data.
Furthermore, it is worth mentioning that the MythBusters experiment only included a small sample size of three individuals, which may not be sufficient to definitively bust the myth. However, the results of their controlled experiment, which utilized sleep-monitoring equipment and moisture alarms, did not produce any wet beds.
In conclusion, while the 'hand in warm water' trick may have some success in causing a drunk sleeper to wet the bed, the existing evidence is largely anecdotal, and controlled experiments have failed to produce consistent results. The potential success of the prank may rely on a combination of factors, including the power of suggestion, the relaxing effects of warm water, and the depth of the sleeper's slumber.

It relies on the power of suggestion
The efficacy of the "hand in water" prank is disputed. While there is plenty of anecdotal evidence to suggest that the prank works reliably, attempts to answer the question experimentally have not been successful.
The myth-busting show *MythBusters* tested the trick on each other and a crew member in a lab with sleep-monitoring equipment and moisture alarms in the beds. Their results were less than impressive: zero wet beds. However, one person commented that the sample size of three isn't great, so the results should be taken with a grain of salt.
If the trick does work, it would rely on the power of suggestion. The sound or image of running water is known to instill a sense of urinary urgency in people with medically or socially shy bladders. Heat and warm water are also a common relaxation modality, encouraging blood flow and providing a soothing sensation after genital surgery. Thus, it is possible that the combination of a deep sleep and the power of suggestion could lead to the success of the "hand in water" prank.

It might work if the sleeper is in a deep sleep
The efficacy of the "hand in water" prank is disputed. While there is plenty of anecdotal evidence to suggest that it works, attempts to replicate it in controlled experiments have been largely unsuccessful. However, it is worth noting that these experiments had small sample sizes and may not have accounted for all relevant variables.
Theoretically, the prank may be successful if the sleeper is in a deep sleep and/or under the influence of substances that impair their judgment. In such a state, the sensation of a warm, wet hand could be mistaken for a full bladder, triggering the urge to urinate. This is known as the "power of suggestion," where the brain associates the feeling of a wet hand with the need to relieve oneself.
Additionally, there is research to support the idea that warm water can induce urination. Immersion of the lower body in warm water and the use of warm water bottles have been shown to relieve post-surgical urinary retention. Similarly, the sound or image of running water is often enough to induce urination in people with shy bladders.
Therefore, it is plausible that the "hand in water" prank could work if the sleeper is in a deep enough sleep for the power of suggestion to take effect. However, it is important to note that the success of this prank has not been conclusively proven, and attempting it may be unethical or invasive.

There is some anecdotal evidence to support the myth
There is a wealth of anecdotal evidence to support the myth that putting someone's hand in water while they sleep will make them urinate in their sleep. This prank has been attempted by many, especially at summer camps and boarding schools, and has been the subject of many online discussions and even a MythBusters episode. While the efficacy of this trick is disputed, some people claim that it has worked for them, suggesting that it is not just a myth.
The purported mechanism behind this phenomenon is the power of suggestion. The sound or image of running water is known to trigger a sense of urinary urgency in some people, and it is believed that the feeling of a hand in warm water may have a similar effect. Additionally, warm water is commonly used as a relaxation modality, and it is thought that the combination of deep sleep and relaxation may contribute to the success of this prank.
However, it is important to note that attempts to validate this phenomenon experimentally have yielded mixed results. While there are many anecdotal reports of success, controlled experiments, such as the one conducted by MythBusters, have failed to produce conclusive evidence. In their experiment, the MythBusters team used moisture-sensitive alarms and sleep-monitoring equipment, but they were unable to produce any wet beds. Similarly, an experiment conducted by the California Center for Sleep Disorders also failed to provide conclusive evidence, as the test subjects either woke up or did not reach a deep enough sleep for the hand-in-water trick to work.
Despite the mixed experimental results, the abundance of anecdotal evidence suggests that there may be some truth to the myth. It is possible that the success of the prank depends on various factors, such as the depth of sleep, the temperature of the water, and the individual's susceptibility to the power of suggestion. While it may not work for everyone, there is enough anecdotal evidence to suggest that, under the right conditions, putting someone's hand in water while they sleep could indeed make them wet the bed.
