Life Sack may be one of the simplest solutions to purifying dirty water that you will ever see. Life Sack is designed to first act as packaging for food supplies, and then as a water purification unit.
After the food in the package has been used, Life Sack can be filled with dirty water which will then be filtered. Jung Uk Park, Myeong Hoon Lee and Dae Youl Lee created this life-saving design, which could make an instant impact if it is ever implemented. With a life-saving design like this, the question shouldn't be if it gets developed -- but when.
