Do old eggs really float? We test this common “lifehack”

Listen guys, unless you have a huge surplus of pants hangers, Q-tips, dental floss and whatever weird detritus that’s often recommended, a lot of so-called “lifehacks” – those hobo techniques for saving money and/or accomplishing some inane task with “readily available” household objects – are a bit impractical, if they even work at all.

But there’s one, at least, that seems like it could perfectly epitomize the intended convenience of the lifehack: Testing the freshness of eggs by just dropping them into a cup of water. We’ve all got water and a cup on hand and, so long as you’re a sentient human being and not, like, a family dog reading this on your owner’s tablet after you taught yourself English.

But does this egg trick really work? Impressed at having actually found a real, potentially useful lifehack, we took it upon ourselves to test it out. Here’s what we found.

Japanese scientists treat depressed male mice by making them remember happy times with lady-mice

You’ve probably never heard of Susumu Tonegawa before, but now’s your chance to fix that! Tonegawa won the Nobel Prize for Physiology or Medicine in 1987 for the discovery of the genetics behind antibody diversity, and he’s been going strong ever since doing his best to keep all of us ungrateful ingrates healthy.

And now Susumu and his team have recently made another breakthrough discovery: treating depression. They were able to virtually reverse the effects of stressful situations on male mice by having them remember the good times they’d spent with lady-mice. How did they do it? Read on to find out!

Got cat tongue? Tongue tip training tip claims to help you drink the hottest of liquids

Japan has a zillion proverbs involving cats, probably because cats are awesome and add flavour and colour to everything in life. One such proverb is “nekojita” which literally means “cat tongue” and describes people who are unable to handle hot drinks and liquids making contact with their precious pink taste buds.

It’s pretty easy to see where the proverb came from – offer anything hot and edible to a cat and watch the look of horror on their face. But did you cat-tongued-people know that there’s a secret method you can use to train yourself to slurp the hottest of liquids with grace and ease?

Science just proved you can unboil an egg, but what about a reversed boiled egg?

Making news headlines around the globe, scientists were able to unboil a boiled egg. That’s pretty awesome for science, but what does that mean for us, the everyday eaters? Not a whole lot at the moment, but here is another trick with an egg you can do right in your own home. All you need is an egg, a stocking, and some household items and you can enjoy a reverse hard-boiled egg!

Mythbusters: We drive a car over our smartphone to test the protective film

Even today, a lot of people in Japan still prefer flip phones over smartphones. Part of the reason is because smartphones screens–exposed as they are–are a lot more vulnerable and seem to break easily. Take myself for example: after purchasing a brand new Samsung Galaxy S4 last summer, I dropped it once and since then have had a giant crack across my screen.

But with the right case and protective film, your smartphone can, apparently, become practically invincible!

A hospital in China wants to help men empathise with the pain their partner feels during childbirth – by rigging them up to an electronic device that allows men to experience it for themselves. Doctors in Jinan, Shandong Province, use electric shock machines to stimulate men’s abdomens, causing pain that’s supposed to be just as awful as contractions and full-on labour pains.

Sure, the pictures of men screwing up their faces are funny. But on the subject of baby-making in China, this “project” is missing the point.

Japan asks if bananas with Sprite will make you puke, Brazilian comedians answer 【Video】

Last week, we took a look at a deeply moving diaper commercial, and there wasn’t a dry eye in the RocketNews24 office (with the exception of Mr. Sato, whose tear ducts are still clogged with cheese). Today, we’re taking a look at a different video about fluids being expelled from the body.

Wow, that sounds digesting and vague, doesn’t it? Well, to be specific, it’s a video about vomiting.

Hmm…still pretty abstract and nasty, huh? OK, one more try: It’s a video about whether or not eating a banana and then drinking Sprite will make you puke (SPARKLE!).

France vs Taiwan: Which country has more warm-hearted and helpful citizens?

Earlier this month, YouTube user NorniTube uploaded a controversial video of a social experiment which looked at how a person’s appearance can affect the responses they get from the general public. One two different days, he pretended to collapse on a Paris street to see if anyone would come to his aid, on one occasion wearing shabby clothes, on the other dressed in a smart suit. (We’ll leave you to watch the video to find out how it went!)

After watching NorniTube’s video, YouTuber Hei Nan decided to test the reactions of his fellow Taiwanese citizens by doing a similar experiment on the streets of his city. Were the Taiwanese more or less likely to help out that the Parisians in NorniTube’s video? Find out after the jump!

How far across the Tokyo sky can a laser pointer shine?

Although RocketNews24 does not condone misusing laser pointers, we still think they can be pretty cool to play around with like seeing how far across the Tokyo area a laser pointer can be seen. Engineer and astronomy enthusiast Takayuki Ohira recently tried out this experiment on a clear night. How far across the megapolis do you think the beam could be seen? Click below to find out!

Experiment hints that humans aren’t necessarily evil after all

A research group from Kyoto University conducted an experiment into the behavior of babies when shown an animation depicting a scene of bullying. During the experiment, a high percentage of the babies showed a deep interest in the party being bullied. It is thought that the tendency to sympathizing with the weaker party reveals the essentially benevolent nature of humankind.
