This chemical really doesn’t want to exist

From NileRed. Cleanup video on my other channel, NileBlue: https://youtu.be/8zilEg_feZA ————————————————- For this video, I make a chemical called manganese heptoxide, which is an unstable and strong oxidizer.

You can’t smell metal

From NileRed. Pick up a shirt! https://www.bonfire.com/nilered/ ————————————————— Metal has no odor and you can’t smell it. But what are we smelling then? It turns out that it’s mostly a chemical called 1-octen-3-one, which is generated when your skin oils react with metal that you’ve touched. I thought this was really interesting, and I decided…

How Do Pregnancy Tests Work?

From Reactions. There are many ways to find out if you’re pregnant. One is to wait and see. For those of us who are a little less patient, there’s the take-home chemistry kit known as a pregnancy test. But how do a little strip of paper and a few drops of urine tell you whether…

How Does Pepper Spray Work?

From Reactions. Personal safety is something we all should take seriously.

Making raspberry perfume

From NileRed. In this video, I get a bit back into making compounds with odors and scents. I chose to go with Raspberry Ketone, because I thought it was an interesting molecule and the synthesis seemed fun. However, in the future, I think I’m going to venture into the territory of nasty smelling compounds. For…

White, Green, Black, and Oolong Tea: What’s the Difference?

From Reactions. Did you know that many different types of tea come from the same plant?

The chemical trafficlight

From NileRed. In this video, I’ll be recreating the popular demonstration called the Chemical Traffic Light Reaction. Note: I made a mistake in the video. I said the carbonate solution would have a pH around 8-9, but it would actually be closer to 11-12. I was thinking of sodium bicarbonate when I said that. Video…

Making transparent wood

From NileRed. This is probably the longest video that I’ve ever posted on my channel, but I wanted it to be as complete as possible! A few months ago, I saw a video made by AvE where he tried to make transparent wood. After seeing it, I was really interested in trying it out for…

Making Brooker’s Merocyanine

From NileRed. For this video, I decided to make Brooker’s Merocyanine, also called MOED, which exhibits solvatochromism. This means that it its color changes drastically, depending on the solvent that it’s dissolved in. I thought this effect was really cool and I wanted to try it out myself. Also, chemical companies sell it for hundreds…
