Building A Cheap Fish Trap (DIY) For catching fish in the wild.

Step 2 Finishing touches :)

Here you finish it by drilling 04x2mm holes (2 at each side of the top) through the bottle and the top so that the top will fit nicely without any fastener like staplers or pins. This way it's the fishing line that is holding down the top of the bottle.

I know smaller round bottle top may not work this way but the square one works properly. For the ordinary soda bottle you can use 2 staplers on the other 2 side for stability.
