Each page in this set draws from a list you can check line by line: the 118 elements, the 206 bones of an adult skeleton, the named colors of the web, the biomes of the Earth, and shapes from the triangle to the icosahedron. Every card carries one fact, such as an atomic number, a bloom season, a Mohs hardness or a count of faces and edges. Teachers can use the pages to call the next question in a revision quiz. Artists can draw whatever comes up. Writers and game masters can take a flower, a gemstone or a scent to make a scene feel real, and gardeners and cooks can let the plant and vegetable pages choose what to try next. The full list is printed under every picker, next to the source it was checked against, so you can see what might come up before you press.
