- a bottle (I used a cider bottle)
- flat wood offcuts
- 12mm (or thereabouts) drill bit
- rubber "tree tie" (or you could use wire)
- dremel and diamond bit
- bird food
Use the dremel (under water) to cut a small gateway into the lip of the bottle, make sure you don't leave sharp edges. Assemble your wood offcuts so that you have a tray and a back - saw if necessary. Drill three large holes into your back bit - two to hold the tree tie, one to hang. Screw all the bits together, fill bottle with bird feed, use tree tie to secure it...and there you are.
