Does anyone know when this will launch (presuming that as yet it hasn't)? I can find no decent references - but a lot say "at the end of 2021" or "in the first half of 2022". I think it is still on earth. -- SGBailey (talk) 17:41, 20 July 2022 (UTC)


 * Not an answer as to when it will be launched, but I found this https://www.wisaplywood.com/wisawoodsat/ which has regular updates about it. The latest posted in April https://kitsat.fi/2022-04_one-year-after-making-our-project-public-now-ready-and-waiting Modocc (talk) 18:14, 20 July 2022 (UTC)

What would happen if you put activated charcoal in cola or ginger ale?
What about fruit juice or Budweiser or wine? Sagittarian Milky Way (talk) 21:03, 20 July 2022 (UTC)
 * I'm fairly confident that they would taste terrible. {The poster formerly known as 87.81.230.195} 90.199.169.199 (talk) 06:29, 21 July 2022 (UTC)
 * What if you let it absorb whatever compounds it can absorb, removed the charcoal with a filter and then tasted it? Sagittarian Milky Way (talk) 15:30, 21 July 2022 (UTC)
 * It would taste fine, and this is a standard purification method: see Water purification. Mike Turnbull (talk) 15:56, 21 July 2022 (UTC)
 * That would depend on if someone liked the beverage with less of the kinds of substances it adsorbs. Which would depend on what kinds of substances it adsorbs. Sagittarian Milky Way (talk) 17:52, 21 July 2022 (UTC)


 * has this: "Activated, food-grade charcoal became a food trend in 2016, being used as an additive to impart a "slightly smoky" taste and a dark coloring to products including hotdogs, ice cream, pizza bases and bagels.[25]" It may serve as a source of nucleation sites in a carbonated drink, resulting in the release of a large amount of gas bubbles. --Lambiam 07:58, 21 July 2022 (UTC)

Cholecystitis after getting shot in the back?
Other than possibly James A. Garfield's assassination, have there ever been any other cases of a person getting cholecystitis after getting shot in the back? Either a famous person or an ordinary person. Or, alternatively, getting cholecystitis after getting shot somewhere else that's located far away from their gallbladder? 68.4.99.100 (talk) 22:03, 20 July 2022 (UTC)


 * Re: Garfield: I'm talking about this very recent hypothesis, which sounds very plausible: https://www.americanjournalofsurgery.com/article/S0002-9610(13)00297-3/pdf 68.4.99.100 (talk) 22:03, 20 July 2022 (UTC)
 * The article Acalculous Cholecystitis in Viet Nam Casualties, referenced in the cited article, discusses cases where cholecystitis developed after abdominal injuries. --Lambiam 07:49, 21 July 2022 (UTC)
