This cuckoo clock will play a sound and the bird will pop out at the top of each hour FOR 10 MINUTES. The code you need to unlock the ammo can will be displayed under the bird. Please DO NOT touch any part of the cuckoo clock! Note: If you miss the 10 minutes at the top of the hour, you must wait until the following hour. In the meantime, you can check out Adventure Labs outside of the museum as well as inside during business hours. Business hours are Wed-Sat 10am-3pm.
