Little Menaces - Self-Tanner Tiff

This is a literal "Hammerhead" shark created by artist Matt Sanders.

The sculpture is made from 685 reclaimed steel hammer heads and weighs 500 lbs (about 227 kg). It took approximately 2,500 hours of work to weld together. Sanders even used sledgehammers for the eye sockets and ball-peen hammers for the eyes to give it a realistic look.

A scientist placed bait on top of a pencil at location A and moved it a few inches to location B. An ant was shown the bait at location A and brought some of it back to its nest. When it returned looking for the bait it continued to search around point A even though the pencil had been moved nearby. Eventually it enlarged the search area and located the pencil at B.

Squiggly lines show the paths the ant took.
