The fact that the ants change directions does not interfere with the aggregate behaviour of ants, as the spoiler illustrates (in fact, I have just spotted that the image above is a spoiler - for me it was just a copy of the first one!). Hence the time of the last ant will be the time taken by the ant located on one of the extremes and with an initial direction towards the center. With 1000 ants and a 1m stick, that should be close to one hour... Nice riddle.

Why would you think otherwise? Hi,

Why would you think otherwise?
