so just get the peice of tolit paper jammed in there. it takes up alot of room in the pen, and jut lay the end down on a table and press the kenx peice down to compress the tolite paper making it very tight, the tighter the better. then put the bb, or just the spring and then the knex peice and press. it doesnt matter how quicky you push it

If the video dosn't work then read this to learn how to make th bullet. Grab the center of the square shheet and start screwing it into the pen. once it gets all the way in, put the pen on a table(bullet end down) and push down with the knex rod to squish the bullet together. you can reuse the bullet once you fire it.
