If you want to have something to take with you....

Vaporize the pot with a heat gun. With a water bong, get a cut plastic bottle (water bottles are best because they are easy to get over the opening) and get it to slip over the bong. Drill 2 holes in the plastic cap of the bottle. Stick medical tube into the corners of deflated ziplock bags and connect the tubes to the 2 holes in the cap. Vaporize until the bag is full of smoke. My friend does this everyday and has a bag of vap'd pot in his passenger seat as he drives 30 miles to class. No loss of flavor/stale/potency.
