This design sounds worthy of making...

A number of unique and intriguing mousetraps have been designed
throughout history. The best are true marvels of engineering, beautiful
in their mechanical simplicity. One of the greatest has to be
the Perpetual Mouse Trap patented by Colin Pullinger & Sons in 1861.
The model that the Museum of English Rural Life (MERL) in Berkshire, UK
has on display just caught a mouse without any bait.

The staff at MERL came in Wednesday morning to an email
from an assistant curator that read: "There appears to be a
dead mouse in this mousetrap, which is not described as
being there on the database." As Pullinger & Sons claim right on the trap,
it will indeed "last a lifetime."
