In them we can find the biggest selenita crystals (the purest gypsum) in the world, reaching lengths of up to 14 meters. Their transparency and shine, in enormous and unique figures move and captivate. It´s difficult to imagine such an important geographic discovery in the latest years, only compared with the Nile river fountains.

This exceptional place leave us with many scientific and philosophical questions: how and why did they acquire their unique shape and appear in this particular place? How can we protect and preserve them accordingly to their natural environment beneath the water? How can we share a place that is inaccessible for security reasons? What reflections can we make from them as an example of the maximum order facing the general matter´s tendency to disorder and expansion? What can we learn from this place where heaven and hell can be perceived at the same time? Can we explore de cave even it´s dangerous conditions?

Now, due to the interest and effort of several companies and institutions, we can begin to answer this and other questions through the Naica Crystal Project.

Each type of crystal has unique properties that deal with specific issues.

During a healing session, universal energy is channelled through the healer – the crystals magnifying this energy.
It is common to feel physical sensations during a treatment, which can range from tingling, sense of heat or cold, sensations of heaviness etc, when energy blockages are moved.

The researchers, led by Masahiro Irie, a chemistry professor at Kyushu University, in Fukuoka, alternately shine ultraviolet and visible light on a rectangular crystal to make it contract and then extend back to its original length. They have also created a rod-shaped crystal that they were able to bend and then straighten up as many as 80 times. When it bends, the rod can push a gold microparticle, which is 90 times heavier than the crystal, through a distance of 30 micrometers.

Previously, Irie invented a type of organic molecule that changes color in response to light; he first described it in the mid-1980s. While studying single crystals of these molecules, his research team found that the crystals also change shape. “We were [very] excited to see the photo-induced shape change for the first time,” Irie says.

Certain polymers and glasses are known to change shape when exposed to light. But this is the first time researchers have seen the effect in crystals, says Tomiki Ikeda, professor of polymer chemistry at the Tokyo Institute of Technology. Their regular structure could make shape-changing crystals useful in various applications. “This means that one can induce a precise change in shape,” Ikeda says. “Every time, you will have the same change in shape upon exposure to the same light with the same intensity … which is very important for precise control of mechanical work in micrometer-sized devices.”

The beer was a kristall style wheat beer, which means the beer is brewed using wheat malt and then filtered for clarity. The major difference between this style of wheat beer and “hefe” style wheat beers is the yeast. “Hefe” means yeast in German, and hefe style wheat beer is a beer brewed with wheat malt in which the yeast is left in, so the beer can bottle condition with the yeast. This makes the beer cloudy when poured into a glass and adds a distinct ester flavor and aroma.

I poured the Weihenstephaner Kristall Weissbier into half liter Weizen glass. The color was light gold, bright and very clear. The head was white and high. The nose contained a subtle aroma of spicy German hops and was very similar to a good light pilsner with a hint of wheat. Many of the reviews for this beer I read described the nose as having hints of banana’s and spice like a Hefeweizen
