The story is about Mr. Waters who works at the municipal waterworks. Every day, he walks through a grey, unfriendly town and one day it occurs to him he could actually send bright colours through the waterpipes to make people happy. He pours the rainbow to the water and goes home as usual. While still on his way, the colourful fantasy is running through the pipes and flooding the entire town. In the end, there is nothing else but colours and all ordinary things disappear.
