I am going to tell you that really cool metal called Gallium. It looks a bit like Mercury and it turns into a liquid at about 30 degrees centigrade. That's about 85 Degrees Fahrenheit! (now that's warm) It's often used in the production of semi-conducters and in some LEDs (The More You Know) And when I got mine they came in a plastic test tube . You can see, at room temperature is solid and it won't flow out at all... So, I'm putting mine in a bowl of warm water to raise the temperature, After a few minutes, if you take it out you could see it's actually turned liquid. I'm tipping this out straight onto my hands. Which i've read it's safe to do so. But if you tried this, you may want to consider wearing gloves! And you can see this core from the center of the test tube which didn't have time to melt yet. (let's put it in the bowl of water to melt it) It feels a little wierd and it's sort of blobs together in the palm of your ha

Everyone's imagination was running wild. Would electricity become free? Could nuclear power help settle the Antarctic? Would there be nuclear-powered cars, planes, or houses? It seemed that this was just a few years of hard work away. One thing was certain: the future was atomic. Just a few years later, there was a sort of atomic age hangover; as it turned out, nuclear power was very complicated and very expensive. Turning physics into engineering was easy on paper, but hard in real life. Also, private companies thought that nuclear power was much too risky as an investment; most of them would much rather stick with gas, coa
