Basically, using a toilet tissue roll, he crafted a tunnel and placed peanut butter at one end of it. After that, he sat the peanut butter roll on top of a counter, and placed a pail under it. Apparently mice love tunnels.
Many people have posted their ideas to modify the same mousetrap.
MAKE Magazine has a comment which involves a can, a pail and some wood.
I'll have to try it out sometime.
