This is pretty basic stoner knowledge, but it’s for those that don’t already know.
Gather the supplies, a pen and a sheet of aluminum foil that’s about 10×10.
Fold up the sheet of foil until it’s a smaller size, as shown.
Place your pen and index finger on the foil.
Roll the foil around both your index finger and the pen.
Make sure the foil is tight around the pen, except for the bowl piece.
Fold up the bowl piece you created with your index finger so it doesn’t suck through when you smoke it.
Test the air flow by taking a hit with nothing in it.
If there is too much air flow, pinch the bottom of the bowl piece to close it.
This is the finished product, happy smoking! 8D
