Forum Game: Guess that foundable!
You, as a community, have 20 yes or no questions to guess that foundable. If someone guesses in 20 questions they win! If not, I remain the champion...
So that you can add intervening comments all official questions should start "Question:".
You don't have to wait for the answer to the previous question to post a new question, but I'm not giving you your question back.
I'm thinking of a foundable, can you guess which one?
