Question:

How can I block copper/alumnium from being detected by a metal detector?

If I am carrying an aluminium bagand someone is using a detectorhypothetically, how can I defeat them ?

Answer:

Boil them till they're just doneTake out of waterGrill on both sidesVery good and tender.
DO NOT boil, you lose all flavor place in oven proof dish, sprinkle with a little (1Teach vinegar,any you have, and sugar, and pickling spice) cover with lid or foil bake 325' for at least 2 hours if thawed, 4 hrs if frozen then apply your bbq sauce and place under broiler till bubbly
place ribs in a roast pot with 3cups of water put in oven for 15 min at 350 coverd Take out of oven and dump out water In a bowl mix together 1 cup of ketchup 1 cup of brown sugar 1/4 cup mustard pour mixture over ribs put ribs back in the oven uncovered for 30min ribs will fall right of the bone
Do you have a crock pot? Put the ribs in it, with some quartered onions, cover with barbecue saucePut it on low heat for 4-6 hours, and you will have very tender ribsIf you don't have a crock pot, you could do this in a large stock pot on the stove, or a large, deep baking dish that is covered with foil in the oven.
put your aluminium bag inside a steel boxThen they will only detect the steelIn principle, you could make an active device with thousands of small antennas or magnetic coils that would nullify the detection field like noise cancelling headphones, but good luck with thatIt's probably beyond current technology and you have a boatload of electronics and wires instead of a regular case.
