The crow came to the table, and saw the meat, but couldn't
reach it. Then it went over to the container with the longer
stick, it couldn't reach that either .. the short stick was not
on the table. Then it started looking around, and saw the shorter
stick dangling from the piece of string. After a moment or two,
it flew up to the branch, started pulling up the string, removed the
short stick from the string, and proceeded as in Level 2.
Wow .. Level 3.
Pretty cool, no?
