Now take the bottom of you bottle and using the tip of your scissors or screwdriver, make small holes on the dimples. This will allow water to freely flow through the fish trap bottle. Take the top of your fish trap and insert it into the body of the bottle. Then using the same technique used to make the holes in the bottom, proceed to make holes through the walls at the top.You may want to mark where your holes will go while the trap is assembled and then dismantle it to make piercing the holes easier. These holes will allow us to put our string through and secure the top.
