Created by engineering students.This is the world's smallest working aquarium - which holds just two tea spoons of water. The miniature wonder, which is made of glass and measures just 30mm wide by 24mm high and 14mm deep, can be held in the palm of your hand. And it is so small there is only room for these tiny zebra fish. --
