Put water in a container and roll it.
In Africa, water transportation is mainly handled by women and children. The Q drum helps transport water easily and quickly. It can be transported while rolling, not lifting a heavy water bottle, and it can carry more water than an existing water bottle.
The Q drum can be used for more than eight years even if it is used every day, and even if the rope pulling the Q drum is broken or lost, it can be easily replaced locally.
