In this video, the narrator follows up on a previous video about aluminum and mercury by testing out some questions posed by viewers in the comments. The tests include seeing what would happen if the air was removed during the reaction, growing the towers upside down, and doing the reaction in multiple spots and having the towers collide. The narrator explains the process and shows the results of each test. The video ends with a thank you to Patreon supporters and their names are displayed on-screen.
Sure, here are the key facts extracted from the text:
1. The author is conducting a follow-up experiment related to aluminum and mercury.
2. Some viewers pointed out the author's incorrect pronunciation of "aluminum."
3. The tower being grown is made of aluminum oxide, formed as mercury exposes fresh aluminum to air.
4. Viewers asked what would happen if the air was removed during the experiment.
5. The author attempted to run the experiment in a vacuum chamber to remove air.
6. Despite using a vacuum, the reaction continued due to small amounts of remaining oxygen.
7. The color of the tower changed when the vacuum was applied.
8. When air was reintroduced, the growth rate of the tower increased.
9. The author observed dark bands forming each time the air was removed.
10. The author theorized that the dark bands resulted from mercury being pulled along with the growing fibers.
11. The author experimented with growing towers upside down and from multiple spots on the plate.
12. Towers grew thicker when the plate was accidentally knocked.
13. Towers weakened at their base and eventually collapsed in some cases.
14. Towers merged when grown from multiple spots simultaneously.
