Tianjin Science and Technology Museum
The Museum of Science and Industry is a great way to pass the day with kids. Interactive exhibits and free admission make it an easy, entertaining afternoon.
Many museums in China can be hard to follow for non-Chinese speakers, but the Science and Industry museum wins rave reviews for being well-maintained, super hands-on, and actually fun. For example: Ride a square-wheeled vehicle over a toothy track, practice dental hygiene by brushing a set of giant dentures, and form metal shavings into sculptures with giant magnets (pictured).
