Space is a strange place ... used to a world where there are the concepts of "up" and "down", with bodies that are the result of the evolution of life in an environment dominated by gravity and surrounded by physical and climatic phenomena are also conditioned by this fact, away from Earth , and touch, if only fleetingly, the ocean star, involves facing strange situations for an earthling. Let's look at six of the most curious. 1) boiling water in one big bubble : Anyone who has ever cooked (or at least has done a cafe) will seen something so basic is boiling water in a container, a simple process in which the heat source below a convection current generated by the weight difference between hot and cold water, since the latter tends to float to the top, cool and fall again, to restart and in cycle.
But this, as was found in an experiment conducted aboard a Space Shuttle does not occur in space, something that now seems obvious: Both the convection and buoyancy are directly linked to gravity, which governs cycle of ascent and descent, and so everything happens in a very different way ... not a small stream bubbles rising to the surface, but in its place is a single, huge and stays in the background, then, obviously, there is no "up" to where you can climb or a gravity that makes a difference in fish ..
2) Fire circular : Something similar to the fire, where the absence of a convection process and, thus, differentiation between hot and cold air prevents the rise in flame shape, as are used in Earth. A candle burning in the area (within a room air, of course) show a more than curious, almost magical, forming a plasma sphere around the point of ignition.
3) More numerous and more lethal : One of the biological enigmas arising from the absence of gravity that scientists have been investigating its effect on all types of bacteria whose colonies grow much faster (up to twice in some cases) than those located on the surface, and can be more dangerous to health. Are profound changes in the case of an experiment carried out with bacteria Salomella recorded changes in 167 genes.
There are several possible explanations for this strange behavior the most interesting of which involves the action of a protein, Hfq, whose function is to control the activity of genes. It is believed that mechanical stress provokes the microgavedad bacterial cells, especially the way fluids move on their surfaces, makes the Hfq into a "survival mode", making them much more aggressive .
4) A bad place for a beer : And is that when gravity is absent family causes the bubbles we see in it or in any type of carbonated beverages, and that the Earth rise and disappear in glass surface, are retained in their internal there is nothing that push up ... as a result becomes a mixture of small spheres of gas and liquid rather indigestible, since the same is happening in the container goes into the stomach of the astronauts who make them, that neither can only erupt to leave that pesky gas.
5) A rose scent space: It is certainly the quintessential flower, the most cultivated and gifted the world, and therefore with countless varieties for sale, some really unique ... but none can compete in this area with a rose that has grown in space because their flavor is unlike any of their 'sisters' land. And is that weightlessness has a curious effect on her changing the oil it produces and that are responsible for its characteristic odor. Needless to say, not something that can be found in stores ... but the roses of the future sellers might make good business selling them to love to travel full moon (literally) of Honey.
6) sweats in orbit : If you do not like sweating possibly space is no place for you, all thanks to the absence of convection currents, which causes the heat generated by a human body does not rise to through the skin, but remain inside. The answer to this situation by our body is cool to sweat abundantly ... what is even worse for astronauts, as there evaporates in the form of drops, but simply accumulates on the skin, making the trip quite humid.
What on Earth in a column of bubbles rising in the space manifests itself as something very different, as we see in these comparison shots ... both are doing exactly the same but the differences are dramatic. 
to romantic dinners by candlelight would be possible in space ... but it is clear that they would not have the same charm. 
The Vostok 4 Pines Space Stout Beer, beer designed for astronaut, with lots of flavor but very little ... and that is carbonated soft drinks and weightlessness are not good friends.
