From the article:
> Aluminum is not a great conductor—it heats up when a lot of power is pushed through it—so a snack bag would potentially melt if it was used to try to block a strong radio signal from inside. But the signals from GPS satellites are weak and can easily be interfered with, intentionally or not, in many ways.
I imagine that if the twisties bag had been grounded, it would be even more resistant to melting if the signal had been too strong for it.
- asteli 9y agoWhat a load of nonsense. Aluminum is a great conductor of electricity. Not as good as copper, but good enough that it gets used as the conductor for high tension power transmission lines. Additionally, you’d need a far more powerful radio than a cellphone would contain to melt a plastic bag. A cellphone radio is what, 3W? You might threaten the bag if you focused all that energy in a dime sized spot on the bag, but a cell radio is intentionally a roughly isotropic radiator.
