Testing the purity of gold from dirt

From NileRed. Ok so we just finished panning for gold using a bunch that Reggie bought off the internet, and by some miracle, we were actually able to get some gold. That being said, I don’t know why, but I’ve always assumed that gold is pure (24k) when found in nature, but that might not…

Finding gold in dirt

From NileRed. A while ago we tried to use our XRF gun to figure out if there was any gold in pay dirt that Reggie got off the internet. Unfortunately the XRF gun said that there’s little to no gold in the dirt, however in the comments, there were mentions about panning it instead. #shorts

Everyone is Wrong About American Coke

From Reactions. Our last video about Mexican Coke made a bold claim: that Mexican Coke has no (unhydrolyzed) sugar in it. Two chemistry professors called us on that claim, so George visited them to run definitive tests on their expensive instruments… and he accidentally discovered that Coke is doing something they haven’t told ANYONE about.…

Infusing apples with different flavors

From NileRed. A little while ago we were successfully able to make an apple taste like just about anything. However, some of the flavors absorbed into the apples much better than others. So, to give the weaker flavors a better chance, we’ve decided to soak the apples for a full 24h. #shorts

Making Citric Acid at Home is Easy (EMOTIONAL DAMAGE)

From Reactions. While it looks easy on paper to make citric acid at home, Chem Thug runs into some pitfalls trying to extract it from some citrus fruit and mold broth. Even though we discovered getting it out of lemons more than 200 years ago, it’s still tricky chemistry to pull off. Watch him struggle…
