春天潮濕，上學或戶外考察，都難免會給蚊蠓叮咬。市面上的蚊怕水可能含有破壞環境或不安全的成分，化學學會和本會合辦天然蚊怕水工作坊，同學們一同製作蚊怕水，學習它背後的化學原理和市面蚊怕水對生態帶來的影響。

Humid spring time always bring about endless mosquito bites, from schooling to field trips. Collaborating with Chemistry Society, the workshop teaches our schoolmates to make natural repellent, and also the chemistry behind and how substances in common repellents pose harm to our environment.
