Little did she know I had trained for this moment four years.” Left: clear ziploc bag with 17 cubical food objects in a 4×4 square, but the extra one prevents the bag from closing. Right: The same 17 food objects arranged in the highly irregular but densest known packing of 17 squares into a square, found by John Bidwell in 1998. The bag is closed and zipped.
