Simplest DIY wormery

This article and video show how to make the simplest possible type of home-made wormery – it just uses one plastic box and a couple of bricks/wooden blocks.  This design doesn’t have a system to collect the worm liquid, so ideally stand this over a collecting tray, another plastic box without holes in, or a sheet of polythene cunningly fixed up to drain the worm liquid into a collecting bottle.
