Nobody would refuse a trip around the world, but the premise is to have enough money and also a lightweight backpack. Otherwise, you’ll walk with a slow dragging motion…So why not replace the big torch with the FLEXI lightweight LED lights? As a collaborative work of Kyeore Kim, Jaesuk Han, Sungkuk Hong and Sena Joo, the flexible light is made out of a thin rectangular silicon pad, with a powerful but energy-efficient LED lights on the edge. It can be rolled up into different shapes, to serve as a directional light or a flashlight when needed. But in most conditions, the kids prefer to make it open like a sheet and use it as an ambient illumination.
