Ever notice how in horror and science-fiction films, there’s a mad scientist who does crazy things like use lightning to resurrect the dead, keep specimens’ severed heads alive, use their children in dangerous experiments or build robots that can do things that robots shouldn’t be able to do. That mad scientist caricature cliché, it turns out, is based on truth. Here are a handful of the most baffling, weird, and downright insane experiments that have all been carried out in the name of science…
![Sergei Brukhanenko tried to keep severed animal heads alive. Brukhonenko arguably helped pave the way for VENOUS PUMP modern heart and lung machines. He advanced medical science in a ARTERIAL PUMP' profound way, and probably saved the lives of countless human beings. Yet history will always remember him as that guy who cut the heads off dogs to see if he could keep them alive. As it turned out, no. He could not.

![SOME PEOPLE CAN'T FEEL FEAR. DUE TO A BRAIN CONDITION. SCIENTISTS TRY THEIR BEST TO SCARE THEM ANY WAY. They eventually discovered even the clinically fearless can indeed be spooked. Just mess with their air. Breathing high levels of CO2 made research subjects feel fear, and then panic. Note that these subjects did not previously know what fear even felt like.

![TWO PSYCHOLOGISTS BUILT A VISUAL CLIFF. A GLASS SURFACE LOOKED LIKE A SUDDEN DROP. One at a time, they plopped a bunch of babies on the cliff and had their mothers coax them across the glass. In other words, they had mothers tell their babies to do something that the babies believed was certain death. Most crawled away from their mothers.

![Scientists spawned tadpoles with eyes on their tails. Tufts University researchers wondered what would happen if they transplanted a tadpole's eyeball from its head to, say, its ass. They found that with the help of a neurotransmitter drug triggering new nerve growth, the tail-eye could actually see. Dr. Alphonse Mephesto of Colorado has expressed his complete support.

![Psychology professor Clarence Leuba wanted to know if laughing when tickled is an innate response, SO he performed experiment's on his own children. For seven months after the birth of his son, Leuba and his wife refrained from laughing when tickling their child. The baby would still laugh, proving this is an innate response. Leuba repeated this experiment with his next child, and got the same results. GRACKED.COM](https://s3.crackedcdn.com/phpimages/imageset/7/9/9/796799.jpg)
![18th century scientist Stephen Gray had observed that an electric charge can travel great distances through single, or multiple objects. To demonstrate he suspended a child dubbed The Flying Boy who was charged with electricity by means of a rapidly spinning sulfur globe, enabling him to do tricks. Fig.s a These tricks included turning a book page without touching it, and a finale where a volunteer would get zapped by touching the now highly charged-up boy.

![CRACKED.COM In 1960, psychologists Eleanor J. Gibson and Richard D. Walk devised an illusory cliff contraption to see if babies' survival instinct would kick in. The mothers stood on the other side of the cliff and asked their babies to crawl to them Out of 36 babies tested, only 3 of them willingly went over the cliff while the rest cried in distress, who probably grew up to have trust issues with their moms.](https://s3.crackedcdn.com/phpimages/imageset/8/0/4/796804.jpg)
![Scientists created remote-contralled (living) beetles. In the never-ending quest to humiliate nature, scientists from UC Berkeley and Nanyang Technological University have turned living beetles into their slaves. By connecting electrodes to the insects' brains, legs, and flight muscles, the researchers can remotely control these biobots for use in surveillance or to search disaster zones for survivors. The beetles emerge from the ordeal completely unharmed, but embarrassed. Probably. CRACKED.COM](https://s3.crackedcdn.com/phpimages/imageset/7/9/7/796797.jpg)
![SIX DIFFERENT MISSIONS TOOK NEWTS. TO SPACE. WE WANTED TO SEE HOW THEY MATE, AND HOW THEY HEAL. Their fertility- -much like that of humans- went a little haywire, and.the space trip initially seemed to do nothing for their healing abilities. But once they returned to Earth, they actually appeared to heal faster. CRACKED.COM](https://s3.crackedcdn.com/phpimages/imageset/8/0/1/796801.jpg)

![NASA SENT FLATWORMS TO THE SPACE STATION. SCIENTISTS CHOPPED A BUNCH OF THEM UP. One middle segment grew a new head. Then it grew a second head on its other end. Terrified, scientists cut both heads off to study them in isolation. The middle segment then sprouted two additional new heads.

![A RESEARCHER TOLD KIDS HE TREASURED A TOY. HE GAVE EACH KID THE TOY, WHICH WAS RIGGED TO BREAK. When it broke despite the child's carefulness, the researcher just stared at the kid for a full minute. Interestingly, kids most traumatized by the experiment went on to have the fewest behavioral problems over the next five years.

![1960S KIDS VIEWED A VIDEO OF A CLOWN BEING BEATEN. THEN THE PSYCHOLOGIST SENT IN A REAL LIVE CLOWN. Sure enough, the children happily assaulted the man with punches, kicks, and hammer blows, proving not only that kids imitate aggression, but also that they have a somewhat limited grasp of consequences.

6 Elaborate Science Experiments Done Just for the Hell of It
![Laszlo Polgar believed that anyone can become a genius with early training.' TO prove this, he tested his hypothesis on his own daughters: Susan, Sophia, and Judit, by teaching them how to play chess at a very young age. The three later became chess grandmasters and Judit became the top-ranked female chess player in history. CRACKED.COM](https://s3.crackedcdn.com/phpimages/imageset/8/0/8/796808.jpg)
![In the 1990s, low income minority families in Baltimore, Maryland were GRAON offered federally funded subsidized housing if they would agree to regular blood lead testing for thein children. That all sounds great until you realize that the homes were known to be contaminated with lead and that the Krieger Institute was researching abatement methods.

![Scientists at England's University of Sheffield made 6-month-old babies stare at different faces of macaques to see how well they can recognize faces. As it turns out, they can recognize faces better than-adults. The babies looked at pictures of new, unknown macaques longer compared to pictures of macaques they had already seen. This suggests that babies can recognize monkeys based on their facial features, a thing adults can hardly do. CRACKED](https://s3.crackedcdn.com/phpimages/imageset/8/1/1/796811.jpg)
![In 1939, researcher Clara M. Davis let 15 babies select their own food for 6 years without adult intervention. They were allowed to choose from a total of 33 food items that contained various nutrients. At the end of the study, it was found that all of the babies were healthy, and those who joined the study undernourished were healthy again.

More than 200 students joined, peaking ill a political rally, before Mr. Jones shut it down. CRACKED.COM](https://s3.crackedcdn.com/phpimages/imageset/7/8/6/796786.jpg)
![THE MILITARY LOOSED 330,000 MOSQUITOS UPON GEORGIA. THEN THEY RELEASED TWICE AS MANY IN FLORIDA. The experiment was known as Operation Big Buzz. The aim was to find out how disease- bugs would fare in militarynte they'd use fine), and how many bite (answer: many). CRACKED.COM](https://s3.crackedcdn.com/phpimages/imageset/8/0/6/796806.jpg)
![Scientists built tiny 3D goggles for praying mantises. This mantis isn't just fashionable with its slick little goggles - it's a boon to science. Mantises are the only known invertebrates with 3D vision, and can accurately strike moving prey even when the image beamed to each eye (via the goggles) is different. This mantis-vision research could help future worker robots navigate the world. Or more effectively murder enemies of the hive mind.
