Step 1: Materials
1) 2 Litre Bottles X 2
2) 10' Rope (I used Para Cord (550 Cord as its better kown as) BUT anything works well so long as its synthetic as ropes such as hemp, cotton, etc. will likely rot or mildew easier which weakens the rope and inccreases the chance of your hard work getting washed down the river)
4) A Black Sharpie
6) Something REALLY Pointy
Step 2: Starting The Project
Now your going to punch holes in one of the bottles down where the bottom is. I personally used the little seam like line at the bottom of the bottle as a guide and punched 8 holes perpendicular to each other about 1/4" from the seam. I then cut the bottom off the bottle using the same seam to punch the holes as a guide to cut off the bottom.
NOTE: Heating up the object your using to puch the holes just enough to melt the plastic works wonders and kinda saves a little time.
Step 3: Making The Inside of The Trap
After you punch the holes HEAT PUNCH a starter hole to insert your scissors and cut the top of the second bottle FLUSH with the bottom of the first bottle.
Before anyone out there comments an insult to me about the cap being on the second bottles top, I KNOW ITS STILL ON...ITS JUST IN THERE FOR ILLUSTRATION PURPOSES!!
Step 4: Securing The Parts of The Trap
Then weld the knot to set it in and keep it from coming apart.
Step 5: Final Touches
Take 48" of 550 cord and cut it in half. take the insividual halfs, and tie an overhand loop in each of them. Then take the remaining rope and tie the two halfs to it using an Archer's knot (really any loop knot works, BUT this is what i prefer).
Now heat punch 4 perpendicular holes in the bottom of the trap about as big in diameter as the rope your using...in my case its 550 cord. Then your going to tie the four ends of the halfed cord through the holes. I used the two half hitches knot.
Step 6: Enjoy The Fruits (erm...i mean...fish :D) of your labor
It is best to put the trap i the more shallow water that the minnows prefer (at least thats where i have seen ALOT of minnows) however it really depends on the body of water. Minnows will frequent the shoreline in most rivers, creeks, and streams because the water doesnt flow as fast. Lakes they may frequent deeper water.
Bait is a little tricky...i dont know how many species of minnow are out there but i DO know that there are too many species for me to really care...BUT i am pretty sure they will eat anything. i remember as a kid, i would wade into the lake and soon after i got all settled, BAM!!! there they were trying to eat the hair off my legs. Point is im pretty sure each species prefers different baits, so if one bait isnt producing results then put something else in the trap. Trial and error here.
LASTLY...the length of time...again from what ive seen before, you could have a swarm in your trap as soon as it hits the water. OR you may get nothing at all for 2 hours. refer to the above paragraph if the latter is the case. If you leave the trap in the water too long, a predator (bird, rodent, fish, or other animal) could get a hold of the trap or its potential contents...of course depenting on your game of choice this could either help you or hurt you in the long run...you could get a better bait such as crawfish and hook a huge Aligator Gar, or frogs and hook a Bluegill.
None the less, i hope Yall have enjoyed this Instructable as much as i have enjoyed making it!!
