Pineapple awards celebrate sciences with touch of humor

An "invisibility cloak" developed by a team from Zhejiang University can make a goldfish invisible in water and a cat vanish into thin air.

The invention, made with cost-effective glass materials, won the Pineapple Science Prize for physics on Saturday night in Hangzhou, capital of Zhejiang province.

A number of other low cost gadgets and interesting research were on the prize list, including a mechanical donkey and research on the mate preference of fruit flies, at the ceremony co-hosted by Zhejiang Science Museum and Guokr.com, China's popular science website.
