**Title:** 7 Unique Materials That Seem Like Science Fiction
**Summary:**
A video showcases 7 extraordinary materials, highlighting their remarkable properties and applications:
1. **Ultra-Hydrophobic Material**: Water-repelling surface inspired by the Lotus Effect, useful for waterproofing and self-cleaning surfaces.
2. **Nitrogen Triiodide**: Highly unstable, explosive compound that can detonate with slight disturbance.
3. **Hydrogel**: Absorbs 30-60 times its volume in water, used in greenhouses, agriculture, medicine, and decorative items.
4. **Nitinol**: Shape-memory alloy (Nickel-Titanium) that returns to its original form after deformation, applied in electronics, mechanics, and medicine.
5. **Metal Gallium**: Soft, brittle metal that melts at 29.76°C, non-toxic but extremely expensive ($3,000/kg).
6. **Aerogel (Frozen Smoke)**: Ultra-light, strong, and insulating material used in space exploration, nuclear radiation detection, and thermal insulation.
7. **Magnetic Thinking Putty**: Ferromagnetic putty created with ferric iron oxide powder, interacting with strong magnets in unique ways.
**Purpose:** Educational entertainment, encouraging viewers to engage and share their thoughts on the most amazing material featured.
Here are the key facts extracted from the text, numbered and in short sentences, excluding opinions:
**Ultra Hydrophobic Material**
1. Ultra hydrophobic material has minimal interaction between solid and liquid.
2. The material's hydrophobic surface is based on the Lotus Effect.
3. The Lotus Effect was discovered in the 1970s from observations of the lotus leaf's natural hydrophobic properties.
4. Research aims to find a material with the highest level of water repellency for industrial applications.
5. Ultra hydrophobic surfaces can protect devices from water damage and walls from dirt.
**Nitrogen Triiodide**
6. Nitrogen triiodide is a highly unstable chemical compound.
7. It can be detonated by contact or any disturbance.
8. The molecule consists of one nitrogen atom bonded to three iodine atoms.
9. Nitrogen triiodide is stable in moist, dark conditions but can explode when dried.
10. Explosion releases a purple, irritating, and potentially toxic iodine vapor.
**Hydrogel**
11. Hydrogel is a gel polymer that can absorb water 30 to 60 times its volume.
12. Its size changes under the influence of temperature.
13. Hydrogel is used in greenhouses, agricultural nurseries, and as a single plant substrate.
14. It's also used for medical purposes, tissue engineering, and sustained release systems for medications.
**Nitinol**
15. Nitinol is composed of almost equal proportions of nickel and titanium.
16. It has the "memory effect," rebounding to its original form after shaping, driven by heat exchanges.
17. Nitinol is used in electronics, mechanics, smartphones, robotics, and medical industries.
**Metal Gallium**
18. Gallium metal is a soft, brittle solid at low temperatures and liquid at temperatures above 29.76°C.
19. Body heat can cause solid gallium to turn into a liquid.
20. Gallium retains its metallic color in both solid and liquid forms.
21. One kilogram of gallium costs approximately $3,000 due to high extraction costs.
**Aerogel**
22. Aerogel, or "frozen smoke," is a material used since the 1960s in space travel.
23. It's the lightest solid material, with a density a thousand times lower than glass.
24. Aerogel is 99% air, with silica gel, and is three times as dense as air.
25. Despite its low weight, aerogel is very strong and has excellent heat insulation properties.
26. NASA uses aerogel for heat protection in spacecraft.
27. Aerogel is used for nuclear radiation detection, thermal insulation, and detecting harmful microorganisms.
**Magnetic Thinking Putty**
28. Magnetic Thinking Putty is created by adding ferric iron oxide powder to regular silly putty.
29. This modification makes the putty ferromagnetic.
30. Only strong, ferromagnetic magnets are attracted to and engulfed by this putty.
