ok so i was makin a bong out of this cool bottle i found(this Actually happend like a week ago) but i just now figured this out i drilled a hole in a bottle(glass) and inserted my pen tube i then put on a metal bowl i already had in my kit it worked beautiffly untill i realized there was no carb and i didnt feel like working to drill another hole in it so i get to thinking and i realize that the pens cap fits it perfectly plus its airtight...... so i attach the bowl to it and it wouldnt fit right so i put the mouh peice i had extra on it and it fit great i had just created a home made pull carb bong in like 30 secnds!!!!!! here a crude pic done on paint of how to do it
