Enter a new generation of inventors, innovators, and entrepreneurs who are looking to the edge of discovery...

The Plain of Jars is one of South East Asia’s biggest archaeological enigmas. Who carved these giant megalithic stone jars, and what they were used for, has remained a mystery for centuries.
