I thought about a lot while mowing the lawn and shit, and came with a few ideas.
1. Superjoint.

Get a large diameter straw that's still in it's paper wrapper. Open ONE end. Leave the straw in to hold it's tube shape. Put weed in it. Get something that fits into the ID of the straw and pull out the plastic straw. Pack in some more to make up for the room taken up by the straw. Blaze it.
and that's all I remember. I'll add more soon D:
