- Lake Tanganyika (/ˌtæŋɡənˈjiːkə, -ɡæn-/ TANG-gən-YEE-kə, -gan-; Kirundi: Ikiyaga ca Tanganyika) is an African Great Lake. It is the second-oldest freshwater lake in the world, the second-largest by volume, and the second deepest, in all cases after Lake Baikal in Siberia. It is the world’s longest freshwater lake. The lake is shared among four countries—Tanzania, the Democratic Republic of the Congo (the DRC), Burundi, and [Zambia](/en.wikipedia.org/wiki/Zambia/—with Tanzania (46%) and the DRC (40%) possessing the majority of the lake. It drains into the Congo River system and ultimately into the Atlantic Ocean.
- Psilocybe cubensis (Wikipedia)
Psilocybe cubensis is a species of psilocybin mushroom of moderate potency whose principal active compounds are psilocybin and psilocin. Commonly called shrooms, magic mushrooms, golden halos, cubes, or gold caps, it belongs to the fungus family Hymenogastraceae and was previously known as Stropharia cubensis. It is the best-known psilocybin mushroom due to its wide distribution and ease of cultivation. This mushroom being optimal for home cultivation specifically, as was suggested in the 1970s, is primarily what led to cubensis being the psilocybin mushroom species most common on the black market as a street drug.
