Road Bumps
The Mousetrap: can kill a mouse but cannot cut thread.The wood: either splits or the nails aren’t long enough.Stability: “just make the base bigger.” The solution for any problem: Duct tape.Slide5
Good Riddance, Party Foul.
What started as a “simple idea” turned out to be not so simple. Worked out all of the problems to the point of functionality.Completed the goal and worked well together.
