Who doens't love a good science museum? Whether or not you're with kids or not, everyone enjoys exploring galleries, tinkering with interactive exhibits, and learning something new. You could easily spend hours at the Hong Kong Museum of Science, located in Tsim Sha Tsui. With four floors of exhibition halls, there's a lot to see and do. When you first go through the main entrance on the 1st Floor, you'll find the new Earth Sciences Gallery (opening early 2020), and the Gallery of Electricity and Magnetism. You then need to go downstairs to the Ground Floor, and work your way up. On the Ground Floor you'll find the World of Mirrors, Light, Motion and Sound, plus the Biodiversity Gallery. Going back up to the 2nd Floor on the escalator, you can take a closer look at the massive Energy Machine which takes up the center of the atrium. You'll then be greeted with one of the museum's icons, a DC-3 nicknamed 'Betsy', which was Hong Kong's first airliner, donated by Cathay Pacific. Though bigger kids can definitely get into the exhibitions on the GF, 1F and 2F, the little ones won't be left out, as the 3rd Floor is a dedicated Children's Gallery. There's a work site for construction, fun cloud rings to play with, and hidden animals to find. This popular museum offers free admission on Wednesdays, and otherwise costs for adults and kids over the age of 4. You can make advance reservations online at Klook.
