The hamster wheel lightbulb
Suitable for children ages 7-11, the hamster wheel lightbulb is located within the playground of the School of social etiquette. The frivolity of play for the sake of selfish pleasure is frowned upon in New London. Similar to other playground equipment within the compound, beyond a form of after class entertainment, the hamster wheel serves the important function of lighting up the lightbulbs in the dining hall.
The hamster wheel treadmill can power 3 60W light bulbs with each revolution for 5 minutes.
