    But does it work with the foil? We found lots of metal containers didn’t block the signal. Hell even a pouch advertised to do it still worked.

    Thick metal containers with over lapping lids worked best.

      Heavy duty Reynolds wrap. Fold to desired thickness and you have you wrap it fully without gaps. You’re tying to contain light.
