Make Sodium Metal with Menthol (and a bunch of other stuff…)

Warning: Sodium is a reactive flammable metal. Wear gloves when handling it. Fire safety protocols must be in place. Greetings fellow nerds. Sodium is a very famous and interesting metal that’s highly reactive even with water. It’s tremendously useful in chemistry for such purposes as reducing other compounds or drying solvents. However, being rather dangerously […]

Could Ultracapacitors Realize Their Full Potential…With Laxatives?

Supercapacitors present an amazing opportunity to move away from batteries and into a world where almost instant charging is the norm. But their drawbacks mean we can’t use them widely…yet. Experiments with a new class of materials that are related to soap and laxatives (yes, laxatives) could bring us one step closer to a world […]

Alkaline Earth & Alkali Metals in Water

So starting out here we have magnesium and uh… you see it’s a metal, it’s got a little bit of an oxide coating on here and so it’s got a little bit of black sitting on the surface but this magnesium metal and you’ll notice that when we put magnesium into water we’re going to […]

Get Lithium Metal From an Energizer Battery

Greetings fellow nerds. In this video we’re going to get lithium metal. Our source, is these Energizer Ultimate Lithium batteries. Regular batteries do not have lithium and cannot be used. Alright, our first task is to remove the plastic label and expose the steel casing. Once that’s done, put on some gloves for the rest […]

Des métaux qui Explosent dans l’eau ! – [Science 2.0]

Go ahead… Come on, come on… [EXPLOSION] – [LAUGHTERS] [BADASS JINGLE] Today on Science 2.0, we’re gonna talk about Chemistry, more precisely about what are called Alkali Metals. You’ll see, it blows up. So I like it. Alkali Metals are the first group elements in the Periodic Table, the ones on the left column. [WINKS] […]

DIY welding with batteries (Good or Bad idea)

I mistakenly said Ohm’s law while that was power rule. lol

How to Make a Battery Protection Circuit (over-discharge protection)

Powering homemade projects with rechargeable batteries is actually more difficult than it sounds. This is because most battery types cannot be over-discharged, as doing so may damage the battery and make it unstable. Consumer electronics overcome this issue by using clever battery protection circuitry that constantly monitors the battery’s voltage, automatically switching the device off […]
