Six Daily Things on Earth Happen Strangely in Space Let’s discover six daily things on Earth that happen strangely in space. Boiling water in space creates a big bubble Though boiling water on Earth creates thousands of tiny vapor bubbles, it only produces one giant undulating bubble in space. Thanks to an experience carried out in 1992 abroad a space shuttle, physicists showed that the absence of convection and buoyancy, two phenomena caused by gravity, leads to the simpler face of boiling in space. On Earth, we can observe these effects producing the turmoil in our teapots. According to NASA Science News, learning how liquids boiled in space would lead to more efficient cooling systems for spacecraft and might also be adopted to design power plants for space stations that used sunlight to boil a liquid and create vapor, which would then turn a turbine producing electricity. An experience of boiling water on Earth and in space You sweat more As explained in the case of candle flames, zero gravity means there is no natural convection, which makes body heat not rise off skin. Therefore, the body constantly perspires in an effort to cool itself down. Human beings sweat more in space A rose smells different in space Flowers smell notably different when growing in space because they produce separate aromatic compounds. The phenomenon can be explained that volatile oils produced by plants are strongly affected by environmental factors like temperature, humidity and a flowers age. An out of this world fragrance produced by a variety of rose called Overnight Scentsation was on the space shuttle Discovery in 1998 You cant burp beer Actually, no pushing gas bubbles up and out of carbonated drinks in space because buoyant force isn’t produced without gravity. It means that astronauts can’t burp beer or other carbonated drinks, which makes the beverages less attractive. Fortunately, an Australian company has produced a beverage rich in flavor but weak in carbonation called Vostok 4 Pines Stout Space Beer that can be enjoyed on spaceflights Bacteria grow more and become more deadly Experiments performed for thirty years show that bacterial colonies grow much faster in space. For example, Astro-E. coli colonies grow almost twice as fast as their Earth-bound counterparts. Furthermore, some bacteria tend to become more deadly. According to a controlled experiment in 2007 testing salmonella growth on the space shuttle Atlantis, the space environment changed the expression of 167 of the bacterias genes. Bacteria in space seem to be more dangerous than that on Earth I am 25 years old, and I study materials on education, likes reading and writing. In free time, I often join literature clubs and share my interest with others.
