Lipton aims to increase the penetration of the Bright Herbal Tea, and make more and more consumers realise the healing benefit of improving vision.

The idea is inspired by a well-known optical phenomena: water refraction has magnifier effect. We meticulously designed this teacup with glass to make clever use of the optical principles of refraction. Once the tea is poured, the tiny message at the base of the cup will be magnified, allowing consumer to experience improved readability.

During the sampling period, the custom-made teacup drew crowds, and consumers queued up to sample the product. The sales at hypermarkets increased dramatically by 26-fold, and the e-commerce sales by 286%. Many netizens also tweeted about their eye-opening experience on Weibo.
