If you're looking for some fun education for the kids, the Hong Kong Science Museum has a new exhibition called Ozone Application, which runs until November 6 at the Science News Corner. Ozone is a gas formed from oxygen in the atmosphere as a result of lightning or energy from ultraviolet radiation. In the atmosphere, it serves as a shield, protecting us from UV light. It can also be used as bleach for disinfection and deodorising. However, a high concentration is bad for us. To learn more, head to the museum at 2 Science Museum Road, Tsim Sha Tsui East. It is open from 1pm to 9pm from Monday to Friday, and from 10am to 9pm on Saturdays, Sundays and public holidays. It is closed on Thursdays (except public holidays). Admission is $25 and free on Wednesdays. For more information, call 2732 3232 or visit hk.science.museum.
