Each of the 36 columns in the room has a one-third chance of being empty, a one-half chance of having one sponge, and a one-sixth chance of having two sponges. The walls are a deep prismarine color. There is a slight smell of ammonia. Sponge rooms were first introduced by the Bauhaus school in Germany during the 1920s. The aim was to create comfortable classrooms for students who needed extra help due to poor eyesight or physical disabilities. The rooms were designed to be as uncluttered and clutter-free as possible so that everyone could learn at their own pace. The name "sponge room" comes from the fact that they were usually filled with spongy furniture that could be used instead of solid wood chairs and tables. These sponges were often painted white to match the rest of the room and have holes in them through which wires could be attached. They could also be left as is without any attachments if that's what the teacher wanted her students to experience too. In this image from the 1930s, you can see that the room is completely empty except for some white paint on the wall and a small blackboard where the instructor could write messages for her students. However, not all schools had sponge rooms.
