Ham Radio operators will use most anything for an antenna-including common materials such as aluminum foil.
In this video from David (DL1DN), we see how that aluminum foil you bought for your kitchen can be transformed into a working antenna for the 10 meter Amateur Radio band.
This is a fun and ultra-cheap way to get on the 10 meter band without much effort.

Here are a few comments from David (DL1DN):
Awsome 20cm antenna made of aluminum foil.
I just test this stupid antenna and it works ๐
Check what is possible with QRP and 20cm antenna.
