It’s an 80l trash can.
The inverted lid has small holes drilled in them and act as the rain collector.
Two more pairs of holes, at the edge of the lid and into the container, together with some string keep the lid from blowing away.

You’re spot on about surface area. A 1000 sq ft roof can collect about 600 gallons of water from just 1 inch of rain, compared to maybe 5-10 gallons from that trash can lid. I started with a similar setup and quckly realized I needed to connect to my gutters to make it worthwhile.
