How to make a booster bag (for legal and recreational purposes of course)

Only proper video I could find of how to make a booster bag. Used to circumvent anti-shoplifting AES systems. Please bear in mind 1) I'm not responsible for how others use the information (legal bit out of the way), and 2) /if/ hypothetically, if you were to try to use a booster bag to shoplift, you may want to look into other anti-shoplifting systems which detect foil.
