Nuclear Bombs Testing

Since the time of Trinity, which is the first nuclear explosion in 1945, nearly 2,000 nuclear tests have been performed, with the majority taking place during the 1960s and 1970s. When the technology was new, tests were frequent and often spectacular, and led to the development of newer, more deadly weapons.

Judging from the amount of nuke test done, I just can imagine the amount of radiation human kind had been exposed.

Starting in the 1990s, there have been efforts to limit the future testing of nuclear weapons, including a U.S. moratorium and a U.N. comprehensive test ban treaty. As a result, testing has slowed, though not halted, and there are questions about the future. Who will take over for those experienced engineers who are now near retirement, and should we act as stewards with enormous stockpiles of nuclear weapons? 

Gathered here are images from the first 30 years of nuclear testing.

Cool Mentos-Coke-Powered Car


Surely you're hip to the Diet Coke and Mentos phenomenon of a few years ago. When an enterprising duo realized that the hard-coated candies interacted with the soda in an explosive way, an internet meme was instantly born. Over the last couple of years, though, interest in the parlor trick seemed to wane. Until now.

Fritz Grobe and Stephen Voltz, the two men who helped kick off the fun in the first place, are back, claiming a new record for the longest distance traveled in a car powered by Diet Coke and Mentos: 239 feet.

After dissecting the video, we believe there's a lot more power in the Diet Coke and Mentos recipe to be had, and there must be a better way to stop so much of the fuel from leaking out instead of providing forward thrust. Duct tape, perhaps?

Microscopic Images Of Alcoholic Drinks

All of these impressive photos of alcoholic beverages under a microscope uncover the elements that make up some of our preferred tipples. Similar to photos of snowflakes, each and every beverage is unique, while observed below when zoomed about 1,000 times under a high tech lab microscope.

What you can see in the magnified pictures are the crystalised carbohydrates that have become sugars and glucose. Each image was created by using a pipette of each particular drink and squeezing a drop onto a slide. Then the droplets are allowed to dry out and the slide is placed under the microscope and a picture taken.

It will take approximately 4 weeks for the alcohol to dry up entirely in the airtight container, and the complete procedure may take around 3 months.
