Making Molten Metal In A Bucket π₯ - Preview
Added 2024-10-04 09:26:24 +0000 UTCHi all, here is a preview of our next video, in which Derek conducts an experiment that has never been tried before. Would love to hear what you think!

Chemical bonds don't "store" energy (contrary to what most HS chem textbooks incorrectly tell you). Chemical bonds are actually a lower-energy state than free atoms, which is why energy is *released* as bonds form. Aluminium and Oxygen release a whore bunch of energy, which means you have to pump at least that much energy back into it to break those bonds down. Aluminium Oxide naturally forms on the exterior of the aluminium particles, which means that you must use some sort of energy source to break down those bonds (that's the sparkler-like igniters). Once those bonds are broken, the pure aluminium is free to react with more oxygen (which has been freed from the mill scale), which in turn releases more energy, knocking more oxygen off mill scale and breaking apart more aluminium oxide bonds.

2024-10-05 15:46:25 +0000 UTCOne question thay comes to my mind? Where does the eneegy originate from? Was it "inserted" when the pure aluminum was produced (which would explain the typically very high energey requirement in that industry) or is it a natural "source" of energy?

2024-10-05 13:34:43 +0000 UTCThat photograph at 1:47, when and where was that taken? And was it originally in color or was it a digitally colorized greyscale image? Could we get maybe a date and time caption, and then a reference for it in the video description? Color picture technology goes back to the 1800s, but it was very rare, and it stood out enough to me to wonder where it came from.

2024-10-05 13:25:29 +0000 UTCThe initial frames made we fear that this was another "Let's film something spectaculair for YouTube" video. But it's still "Veritasium quality" with enough history and science mixed in.

2024-10-05 08:09:25 +0000 UTCSuper! Reminds me of The Monkey Wrench Gang, when Hayduke attempts to take down a highway bridge with thermite - but itβs too controlled to destroy.

2024-10-04 18:37:14 +0000 UTCThank you for yet a another super-cool story! I have first observed this several years back in Germany watching a rail repair crew do just that, repair rail, and I have supervised the use of Thermite Grenades in combat to destroy caches of enemy equipment. Both of these activities were pretty cool to be part of, but your explanations for this process bring an absolutely bright clarity this works,

2024-10-04 17:28:32 +0000 UTCOn the transition from liquid iron to aluminum slag at ~12:15, a slow motion view might be useful. Even with the arrows, I had trouble seeing the difference. I really enjoy these practical / experimental videos. Much more engaging than theory. Can't wait to see the other parts of the series.
