Setting the Conibear Trap in a Burrow

What happens here

The host demonstrates the final steps for setting the Conibear trap. He carefully threads a piece of string through the trap's trigger mechanism and ties it to a bait (presumably a small piece of carrot or other muskrat-attracting food). He then shows how the armed trap, attached to its metal stand, is precisely placed at the entrance of a muskrat burrow along the pond bank. He explains that the muskrat will swim into the burrow and trigger the trap when it makes contact with the bait string or trigger bar.

Goal: Deploy a set Conibear trap in an active muskrat burrow.
