You need to make a faraday cage. You can buy Faraday bags Online. Under rare circumstances Tin foil might work. Not pointless To try if you have no choice.
To make a Faraday cage from tin foil, you will need a cardboard box or plastic container, a roll of aluminum foil, and some tape or glue. First, line the inside of the container with the foil, making sure to cover all surfaces including the top, bottom, and sides. Then, take additional pieces of foil and cover any seams or gaps in the lining to ensure that the cage is completely sealed. You can also add layers of foil if desired for extra protection. Once the cage is complete, test it by placing a small electronic device inside and attempting to send a signal to it. If the signal is blocked, the cage is working properly.
Wrapping an object in tin foil can be an effective way to block electromagnetic signals, such as radio waves and microwaves. This is because aluminum foil is a conductor of electricity, which means it can absorb and distribute electromagnetic energy. When an electromagnetic signal comes into contact with the surface of the foil, it causes the electrons in the aluminum to move, creating an opposing current that can cancel out the original signal.
However, the effectiveness of wrapping something in tin foil as a faraday cage depends on how well the aluminum foil is sealed around the object. Gaps or holes in the foil will allow signals to penetrate the cage. The thickness of the foil can also play a role in its effectiveness. Multiple layers of foil will provide better protection than a single layer. Additionally, the frequency of the signal and the distance between the signal source and the object being shielded will also affect the effectiveness of a faraday cage.
It's important to note that tin foil is not the same as aluminum foil, Tin foil is not as conductive as aluminum foil, so wrapping something in tin foil might not be as effective as wrapping it in aluminum foil.
