For people in developing countries, getting clean water to cook with, clean with, and drink, can be a difficult and dangerous task. Piet Hendrikse wanted to find another way. His solution was the Q Drum. Essentially a plastic cylinder with a hole through the middle, the Q Drum can be filled with water and rolled along the ground with rope or even old clothes tied together. The outer plastic is durable so that it won’t puncture during long treks over rough terrain. Empty, the Q Drum weighs just under 10 pounds. Filled with water it weighs 120 pounds.
