The premise that the difficulty is simple: entrants drink a gallon milk as fast as they can, and also then effort to hold it down for one hour without puking. It seems simple, yet the success rate of this challenge is incredibly small. Lots of civilization have make the efforts it and miserably failed, as YouTube is rapid to document, yet is the impossible? No: simply really hard and also kinda gross.


But what renders this difficulty so an overwhelming is the amazing part. Drink a gallon of anything in a short period, even water, is dangerous. When you drink a gallon of water, the overloads the body"s circulatory system as well as the kidneys, diluting blood electrolytes and causing cells to swell. The can even potentially cause mind damage or death. Most people who attempt to drink a gallon of milk in one hour vomit for a variety of possible various reasons.

The very first explanation one could assume requires lactose. That"s a milk sugar, and the person body have the right to only handle a details amount the it.

World who are lactose intolerant have challenge processing any kind of lactose, and also in severe instances could throw up indigenous drinking simply one glass the milk. Yet lactose intolerance, rather of being a stomach issue, is yes, really an concern of the large intestine. Lactose it s okay digested in the little intestine, so those through lactose intolerance face issues in the big intestine as soon as lactose is spend by bacteria, resulting in gas and also diarrhea. For this reason lactose in milk really isn"t what"s avoiding people indigenous holding the milk down.

Calcium is another possible culprit. One 8-ounce (237-milliliter) glass of milk includes 300 milligrams that calcium; because that comparison, a chewable Tums tablet contains 200 milligrams that calcium, so drinking a gallon that milk is prefer eating 25 Tums tablets. This really messes through the mountain balance in your stomach, which gives a really good reason to litter up.

But the key reason why this challenge is virtually impossible comes under to stomach size. An median human deserve to only hold about a half-gallon (1.9 liters) of anything in your stomach. When you push past that boundary, the stretch receptors in her stomach are motivated which cause emergency-overload vomiting.
