Water was here all along

Really, water didn’t come from asteroids or meteorites. The water was here at the formation of the solar system. After the Earth cooled down the water could clump together into oceans and then allow life to form. In fact, we have three oceans worth of water lying right now at 700 miles below Earths crusts […]

How does salt melt ice?

Well it ain’t. It does not melt ice. Salt is just moving the melting point below 0 degrees Celsius and thus you will see water becoming liquid when salt comes into play. The way ice make water liquid is by injecting the sodium and chlorine ions between the water molecules in the ice breaking it […]

How much water do you need to extinguish the Sun?

Fraser Cain has a great video responding to this very question: how much water would extinguish the Sun? The answer is: none, nada. Any water you add to the Sun will make the Sun shine brighter and get bigger and “burn” hotter and faster. The Sun does not burn in the sense that you got […]

If you drink 6 L of water at once you die

The guys at Reactions have created an explained video in which we learn that the dose makes the poison. For example, were you to drink 6L at once, then you would die. You die because of loss of Na ions in your body and thus the electrical activity inside us is decreased. Heart and brain […]

Neat experiment with honey: it will be attracted to a plastic cup when the cup is electrically charged

Thunderf00t tried to explain why does the water get attracted to a plastic cup when you rub it against your hair. It seems that water behaves like an electrically charged medium and people don’t really know why it does that. in order to observe these things better Thunderf00t used honey, which contains water, to see […]

Water inside Earth’s mantle? Un-freakin-believable

Several science websites, among them New Scientists and University of Alberta, have reported that there is water in the mantle, 700 kilometers beneath our feet. Steven Jacobsen of Northwestern University in Evanston, Illinois, says that the water is trapped inside a blue rock called ringwoodite. And that is liquid water, if you ask. Wow, that […]

White hot metal in water? Yes. Bonus: why does sodium (Na) explode in water?

ThuderF00t works in the field of chemistry and he has some videos explaining why Periodic Videos got their explanations wrong. In the video from above you will find out that sodium – Na – does not explode because it becomes too hot, but instead it explodes because of some other, not known reason. When you […]

SciShow about three big discoveries of 2013: Higgs Bosson, water on Mars and Neandertal genome

2013 was a great yer for the guys at SciShow, and for me too. I learned a lot, given the fact that I have another sci&tech blog in Romanian, tehnocultura.ro. 2013 brought us the Higgs Bosson, not such a big surprise after all, and then we found out that there is water on Mars and […]
