Hippo Water Roller
This is a brilliant piece of engineering to make life easier for millions of people: water on in wheels:
Millions of people worldwide are forced to walk long distances on a daily basis to collect their water requirements for the day. Traditional methods of collecting water include the use of 20-liter (5-gallon) buckets, which are laboriously carried on the head. Extensive suffering occurs in the process. This method is very time and energy consuming and is also the cause of many serious health problems.
The Hippo Water Roller was specifically designed to alleviate the suffering caused by a lack of access to water. The Hippo Water Roller is a barrel-shaped container designed to transport 90 liters (20 gallons) of water. It comprises of a drum with a large screw-on cap and a clip-on steel handle.
