It's been suggested that it would be much more welcoming if rules to the ongoing games were readily available. Perhaps we could post here, and English Tea mods could sticky the thread and tidy up afterwards if necessary? I volunteered for the one I started on this version of the board:
Animal, Vegetable or Mineral
The goal of this game is to identify a specific living or nonliving item from the Chalet School series. It may be as big as the Tiernjoch or as small as the weights on the cuckoo clock in Tom's doll's house.
1. The winner of the previous round begins the next with a statement such as "I'm thinking of something animal," or "I'm thinking of something that's vegetable with a little mineral."
2. Players frame questions about the item that can be answered "yes" or "no," although the person who knows the answer is free to qualify the answer.
3. Each player should ask only one question at a time, and wait until that question is answered before asking another.
4. It is fine for players B, C and D to ask their own questions while waiting for an answer to player A's question.
The "animal" category includes persons, animals, and animal products. Leather, wool, silk, feathers, non-vegetable sausages, wasps, and eyes that have not yet needed glasses all fit into this category.
The "vegetable" category includes living plants and detached or cooked plant parts as well as products such as wood, paper, linen, cotton, cork, sugar and castor oil. It also includes the fungi and algae that botanists don't count as plants.
The "mineral' category includes metals, gems, salts, chemicals, rocks, mountains, and bodies of water. For purposes of this game, all plastics have been dubbed mineral, even though some are derived from plant products rather than petroleum. Likewise, fossil fuels and amber count as mineral. It is not necessary to include "mineral" to account for the water in fruit juice (vegetable) or milky coffee (animal & vegetable), since both animals and vegetables contain water.
Have I missed anything?
Castor oil: Triacylglycerol from Ricinus communis containing hydroxy-fatty acids.
