ok im pretty fucking ripped right now and found this out by accident 1. get a soda from like mcdonalds or some good shit like that. use water if your scared of the soda taking some thc or whatever from your hits. 2. drink about half of your lovely soda. 3. take a hit and blow smoke into the straw (make sure it bubbles) until you see smoke start coming out of the spot where the straw goes in. 4. pull your straw out a bit to where its out of the soda but not out of the cup. 5. inhale your flavored and filtered smoke its not really a bong but you get 2 hits kinda like getting shotgunned but one is filtered you dig?
