Lars and Kristin noticed on their travels, especially on the African continent, that daily water is often transported and stored in canisters. The canister is the solution!
For example, Ryszard Kapuscinski wrote in his book “African Fever” (1998) about the achievement of plastic canisters: “In the house, the most important role falls to the children – they have to fetch water. When everyone is still asleep, they jump up in the dark and run to the springs, the ponds, the rivers to fetch water. Modern technology has given these tots something important – the cheap, lightweight plastic canister. […] A miracle! A revolution! First, it is relatively cheap, but the most important thing is that it weighs hardly anything!”
Even today, the water infrastructure would be unthinkable without the canister. However, there is still the problem of water purification, as water sources are often contaminated and unsafe.Even if the water source is safe, the drinking water in the canister might be contaminated, as they are difficult to clean and pathogens can multiply quickly. The local people hardly use water filters, in many cases they boil the water or use chemicals to kill the pathogens and make the water safe to drink.
The question quickly arose in their minds, why there is no simple water filter that is exactly adapted to the “canister culture”?
So the idea of “what a bird” was born!
