A high-tech Faraday cage protects those inside of it and their electronic devices from the effects of electromagnetic pulses. Luckily, a homemade Faraday cage can be created with household items.

Okay, I'm doing a presentation on Michael Faraday for tomorrow's physics class. I looked up on him on the Intarweb, and found stuff about the Faraday cage, and how to make a cheap, homemade one ...

To understand how MXenes make a Faraday cage that can be switched on and off, first we must understand Faraday cages and shields themselves.
