A YouTuber performs various experiments with an aluminum sphere, including:
1. Dropping it from a height to test its durability, with minimal damage.
2. Setting it on fire, which only dulls its surface.
3. Cutting it in half using a machine, revealing a compact and firm interior.
4. Melting the two halves in a homemade foundry to re-cast them into a single sphere.
5. Cooling the new sphere and polishing it to a mirror finish.
Throughout the video, the creator shares their process, provides explanations, and acknowledges comments from viewers. The aluminum sphere is ultimately reformed and restored to its original shape, with some minor imperfections.
Here are the key facts extracted from the text:
1. The host of the video warns not to put metal in the microwave.
2. The host drops an aluminum ball from 5.5 feet to test its durability.
3. The aluminum ball is dropped from a higher distance, around 5.9 feet.
4. The host sets the aluminum ball on fire to test its resistance.
5. The fire does not affect the aluminum ball much, only dulling it slightly.
6. The host cleans the aluminum ball and it regains its shine.
7. The host attempts to cut the aluminum ball in half using a saw.
8. The host uses a press and a cutting machine to cut the aluminum ball in half.
9. The aluminum ball is cut into two halves, revealing its internal structure.
10. The host melts the aluminum ball in a foundry to test its melting point.
11. The foundry reaches a temperature of up to 1000 degrees Celsius.
12. Aluminum requires between 800 and 900 degrees Celsius to melt.
13. The host pours the melted aluminum into a mold to create a new sphere.
14. The host uses a Styrofoam sphere as a mold to create the aluminum sphere.
15. The Styrofoam sphere is buried in sand and replaced by aluminum as it burns.
16. The host sands and polishes the new aluminum sphere to make it shine.
17. The host spends around 4 hours sanding and polishing the aluminum sphere.
