Question Splitting Amoebae

Maxwell Edison is studying a newly discovered hyperactive amoeba which multiplies at a highly accelerated rate. He places one such amoeba in a jar. After 15 seconds the amoeba splits. 15 seconds later the two amoebae split. 15 seconds after that the four amoebae split and so on. After two hours the jar is halfway full. How long will it take to fill the jar completely?

EDIT: You may have noticed this thread was closed as soon as it was created. That was not intended to limit your input or enjoyment in any way. On the contrary, your participation is most welcome. The action was taken to prevent eager Peeps from going into some search engine, finding the answer, and posting it, as happened on several occasions in the past. (Of course I harvest a lot of this material from other sources. You didnít think I create it all myself, did you? Iím good, but Iím not that good!) Regrettably, that also means that folks who legitimately work out their own answers, and would like to post them, donít get to display their prowess, but Iím afraid that canít be helped. Iíll open the thread in a couple of days, when Peeps have had an opportunity to try their hand at a solution, and you can post away then. The official answer will come a bit after that. I appreciate your patience and understanding, and hope you enjoy the exercise.

The Official Answer

15 seconds after the jar is halfway filled (two hours and 15 seconds after the first amoeba is placed into the jar) the jar will be completely filled. Remember, the amoebae double every 15 seconds.
