Water Tourmaline Stone

While bismuth crystals can easily be found online, the watermelon tourmaline" - a crystalline boron silicate mineral compounded with elements such as aluminium, iron, magnesium, sodium, lithium, or potassium - is definitely something you don't see everyday. Supposedly, this is a rare variety that displays 3 different colors in the same gemstone: green (watermelon skin), pink (the fruit) and white (the rind). Similar to the ametrine gemstone, the colors of the watermelon tourmaline occur 100% naturally in nature. Continue reading for more.

Self Healing Concrete

Trying to fix cracked concrete is a pain to say the least, but scientists in the Netherlands have managed to create a bio-concrete blend with built-in bacteria that can repair small cracks and holes in cement. The bacteria is activated by water, and would eat food provided in the concrete mixture to combine calcium with oxygen as well as carbon dioxide, to form what is essentially limestone. To find bacteria that could survive in the high-pH environment of concrete, the team looked to the naturally high pH soda lakes in Russia, and located a strain that fit both of these requirements. The bacteria was formed into tiny pellets to keep it away from the food source until needed. Scientist Henk Jonkers explains that water creates a threat to the stability of concrete: "Water is the culprit for concrete because it enters the cracks and it brings aggressive chemicals with it."

Triton Respirator

The Triton Respirator lets humans breathe underwater without an oxygen tank, as they simply need to bite down on its plastic mouthpiece and let the gill-like arms on the sides of the scuba mask do the rest. Simply put, there are small holes in the material where water is sucked into the inner chambers, which then separate the hydrogen from the oxygen and release it, passing on breathable air. The filtered oxygen is compressed into a micro-compressor powered by a micro battery - 30-times smaller than current batteries. Continue reading for a video and more information.

This appears to be an item from Minecraft, but it's actually a real piece of fluorite, a colorful mineral, both in visible and ultraviolet light. It comes in a wide range of colors and has consequently been dubbed "the most colorful mineral in the world". Every color of the rainbow in various shades are represented by fluorite samples, along with white, black, and clear crystals. Practical uses for this mineral include fluorite optics, which are also usable in the far-ultraviolet range, where conventional glasses are too absorbent for use.

Most meteorites appear jagged with a rough texture, but when you polish one of these space rocks, something amazing happens. Reddit user Isai76 shared this other-worldly image of a polished pallasitic meteorite, in which the green-yellow transparent minerals are called olivine, the material that composes most of the upper mantle of the Earth. The metallic parts you see are an iron-nickel alloy. Continue reading for more pictures and information.
