Make an apple pipe. Take an ordinary apple, and using a key or a pen or something carve two holes: one from the top to the center, one from halfway down the side to the center, so they meet in the middle and make a tunnel through the apple. Then blow out all the apple guts, place a screen on the top hole (stick your finger in any standard faucet to find one) and put the weed on top of that. Toke out the other hole.
