How To Make Galinstan

Let's make some Gallon Stan. Unlike Mercury, Gallon Stan is not toxic, and it's a liquid at room temperature. Unlike Gallium, which is solid up until about 30 Celsius, you have to hold this for a while before it starts getting drippy. No, no, no, you deserve a metal that is almost always wet.

I'm going to need this magnifying sheet. It's a bit floppy, but I can just whip out my tools and build a sturdy frame. The lens can focus the sun's energy enough to easily melt 10. That's great because, by weight, Gallon Stan is 10% tin, 20% indium— the only element you can safely chew like bubblegum— and 70% gallium.

To speed things up, I used my lens to melt the metals down. They began to amalgamate; their respective atoms all get in each other's way, frustrating crystallization. So instead of melting at 232, 156, or 30, Gallon Stan melts at just 11.

I froze some Gallium and some Gallon Stan in my freezer, and watch this! After just a few minutes, the Gallium was still solid, but the Gallon Stan was a nice shiny mirror soup.

Patterns in hundreds chart

So what we have in this chart is all the numbers from 1 to 100 organized in a fairly neat way. It’s a somewhat intuitive way to organize it where each row you have 10. So you go from 1 to 10, then 11 to 20, then 21 to 30, all the way to 100. And what we’…

Rounding to nearest ten, hundred and thousand

At a barbecue to celebrate the end of the soccer season, 1,354 hot dogs were served. Round the number of hot dogs to the nearest 10. All right, let me just rewrite the number: 1,354. Now let’s just remember our places. This is the ones, this is the tens,…

Searching For Life in Volcanoes and Other Extreme Environments | Nat Geo Live

JEFFREY MARLOW: As a scientist, we often go to some of the most extreme places on our planet to collect microbes, bring ‘em back, understand what they’re doing and how they work. These types of organisms can actually broaden our search for life beyond ear…

Worked example: Using the reaction quotient to predict a pressure change | Khan Academy

A one liter reaction vessel contains 1.2 moles of carbon monoxide, 1.5 moles of hydrogen gas, and 2.0 moles of methanol gas. How will the total pressure change as the system approaches equilibrium at constant temperature? So, our carbon monoxide is react…
