First take the guts out of the pen but don't throw them away then take you're knife and cut about 4mm away from the pen enough to slip the ink thing through the bottom.

Now take the spring from the ink thing and put the spring on the other side of the ink thing now slip it down through the top of the pen and through the hole you cut now pull back on the ink thingy and release the ink thingy and should go flying.
