I sat still on the sidewalk watching the ants. There was a sandwich on the hard concrete. They were grabbing huge chunks ten times their size. How could something so tiny be so strong? I reached for a worker ant carrying a hunk of cheese. It climbed my finger and I placed it at the top of the anthill. More ants came to me. I took several at a time, placing them all near the anthill opening. There were so many that I put small pieces of sandwich inside the anthill. When every crumb was gone, the ants went home.
