i am bored and this last years i have collected inmense amounts of knowledge about a lot of things, as i do not have friends interested in some of this subjects i will be talking of in future posts, i have decided to bless the juno comunity with easy to understand science facts that i hope you guys can share with anyone interested or just adquire some culture, have fun!
as i used the description to explain the nature of this and future posts, ill write the day 1 fact on this comment.
Hydrolox is a type of rocket fuel used in some engines and obtained by separating the oxygen and hydrogen atoms from H2O molecules. hydrogen acts as the fuel as it is explosive, oxygen is needed for combustion, so both elements are used on the fuel. something curious about hydrolox is that when burned, it forms H2O molecules again, so it does not produce any pollution, however it creates clouds and yes, it causes rain! this was proven in NASA's testing of the RS-25 engines on the SLS launch system, whose exhaust clouds caused precipitations after the launch.
You cannot make a rain machine but you can mke your own hydrolox. it is a very easy thing to do, you just need a glass of water, a battery, and two pieces of metal (a paper clip is fine). unbend the clips so they are just a small metal bar and then tape each clip to one side of the battery (preferably a 9 volt one), make sure they do not touch eachother. introduce the clips into the water, avoiding touching it with the battery and leave it there. after some seconds, small bubbles should appear around each clip, the ones around the positive terminal are hydrogen bubbles, wait until you have enough of them to collect them in any way, if you light a match and put it next to the bubbles, they should combust, but as the amount is quite small, you will not see any flames as it will more likely be an explosion, the explosion is not dangerous, you can fill your hand with a bubble of its size and the bang wont hurt you, anyway i advise that the explosion is quite loud and can hurt your ears if you attempt a big one, try not to exceed a hand sized bubble
