The Fun Theory

Public washrooms are not generally places known for being pleasant or hygienic. Part of the problem is people neglecting to flush the toilet after they have finished their business. This device will encourage toilet flushing with prompts and a prize (of the non-tangible variety). When a person enters the stall, a screen above the toilet will pose a question. These can range from riddles to true or false questions. The answer to the question will only appear once the toilet has been flushed (triggered by a cord, attached to the device). Accompanying the answer will be a dazzling array of light and sound, a true reward for discarding refuse.
