Here's what I used, it works GREAT. Get a CCI .22 plastic ammo box, the kind that holds 100 rounds. Carefully clean it out. It's perfect because it has a plastic cover with 100 holes, just right for ventilation and keeping the beads from falling out if you tilt it.
So start with this....

Now here's the box with beads in it. Finally just snap on the plastic lid with the holes and we're done...

OK, ready to smoke!!
