I had previously followed many designs for soda bottle fish trap and many does not drain the water out when the trap is pulled out of the water. This is my very own design that allow you to quickly get more fishes as the fishes don't swim out of a over-flowing bottle and eliminated the weight of the trap as the water flows out easily at the bottom.
You need the following
1. A clear plastic bottle (preferably larger types)
2. A scissor
3. A Drill or sharp scissor to make hole
4. Some nylon or ropes
5. fishing line
This is my first instructable post so pardon my newbie-ness!
Step 1: The Drainage Netting :)
The difference between my design from the usual fish trap is here...the bottom drainage system. Simply use a cheap stainless steel netting for washing vegetables for this part.
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.
Step 3: Test the Fish Trap :)
