If you’re going to use a bowl piece, widen the hole until the bowl piece fits.
Instead of foil, use a socket for a socket wrench, a thimble, or another circular piece of metal that you can use to hold your smoking substance. The danger from using foil is a common myth, but the foil does not release enough aluminum during smoking to cause harm to you.
While sockets and other metal can also use foil, you can line the inside of the socket with metal mesh to create a bowl.
Instead of a bottle, you can simply use a large container such as a bucket, coffee pot, pitcher, or stopped sink, You won’t have to cut these.
When picking up the cap, make sure your substance of choice isn’t falling through the holes in the foil.
