dude, there is so many things use instead of aluminum foil. i will addmit that i have used cans and foil in despret times many of times. but it just ruins the flavor of your herb and can give you althimers. no good. if you have to just take a sink screen from a gas station or restraunt. there is usually two sink screens in a sink faucet but if there is only one i wouldnt take it from your own home bc it makes the water come out fast as hell. like it shoots out. u can also take the end of a jellpen, the metal part and pack the weed in there, the holes small enough and stick it into another tube but make sure it fits snuggly, u dont wanna lose smoke. its a small bowl but its better than aluminum shit.
