A possible concise summary is:
The video is about a person who tries to make carbonated water using diamonds, which are burned with oxygen and turned into CO2 gas. The person explains the history, chemistry and process of the experiment, and shows how they built a pressure chamber and connected it to a soda maker. The person tastes the diamond water and finds it no different from regular soda water, but still thinks it is cool and interesting. The person also gives away some vials of diamond water to the viewers.
Here are some key facts that I extracted from the text:
1. The text is about an experiment to carbonate water using diamonds as a source of carbon dioxide.
2. The author bought 5 carats of uncut white diamonds for $47 on eBay and burned them with oxygen using a quartz tube and a blowtorch.
3. The author collected the carbon dioxide gas by freezing it with liquid nitrogen and turning it into dry ice.
4. The author used a pressure chamber and a SodaStream machine to inject the carbon dioxide gas into a bottle of water.
5. The author tasted the diamond water and found it indistinguishable from regular carbonated water.
6. The author gave away some of the diamond water to his friends and offered three vials to his viewers through a giveaway contest.
