Fiery Cauldron (Halloween) - Periodic Table of Videos

TL;DR

Sam and Neil conduct an experiment using a hemispherical analyzer to react red hot charcoal with liquid oxygen, resulting in a controlled and visually stunning reaction.

Transcript

Sam and Neil have devised what to me is a new experiment for Halloween it's something that involves the use of Neil's cauldron so here it is this is a hemispherical analizer from an old XPS machine so XPS is x-ray photo electron spectroscopy Neil has salvaged this piece of metal and added legs to it so he's meleed his own which is cauldron and we'r...

Key Insights

• 🤘 The experiment involves using a hemispherical analyzer made from salvaged metal and a cauldron.
• 😅 Red hot charcoal is reacted with liquid oxygen, resulting in a visually stunning display of a glowing white hot charcoal.
• 🫗 Liquid oxygen is dangerous due to its concentrated oxygen content, making things burn dramatically.
• 😅 The reaction between red hot charcoal and liquid oxygen is controlled and allows for observation of the reaction process.
• 🫢 The floating effect of the charcoal on the liquid oxygen is due to the high temperature of the charcoal, causing it to be surrounded by oxygen gas.
• 🥵 The reaction releases a significant amount of heat.
• 🤔 The experiment offers a slower and more satisfying reaction compared to explosions, allowing for time to observe and think.

Questions & Answers

Q: What is the purpose of using a hemispherical analyzer in this experiment?

The hemispherical analyzer is used to contain the reaction between red hot charcoal and liquid oxygen, allowing for a controlled and observable reaction.

Q: Why is the reaction between red hot charcoal and liquid oxygen dangerous?

The reaction is dangerous because liquid oxygen is highly concentrated oxygen, which has a tendency to make things burn very dramatically. The reaction can result in intense heat and flames.

Q: How does the reaction between red hot charcoal and liquid oxygen occur?

When red hot charcoal is dropped into liquid oxygen, it reacts with the oxygen, causing the charcoal to heat up even more. This results in a glowing white hot charcoal and the release of a significant amount of heat.

Q: Why does the charcoal appear to float on the surface of the liquid oxygen?

The charcoal appears to float on the surface because it is so hot that it is not in direct contact with the liquid oxygen. Instead, it is surrounded by a cushion of oxygen gas, similar to how water droplets can float and vaporize on a hot metal plate.

Summary & Key Takeaways

• Sam and Neil set up a hemispherical analyzer, made using salvaged metal and Neil's cauldron, for a Halloween experiment involving liquid oxygen.

• The experiment begins with setting up a small barbecue and placing pieces of homemade charcoal in the cauldron.

• The reaction between red hot charcoal and liquid oxygen creates a visually mesmerizing display, with the charcoal glowing white hot and giving off a significant amount of heat.
