Cassette demagnetizer
Here’s something that would probably leave you utterly surprised. This round-shaped object with a cable coming out of one end looks like it could wreak some serious havoc in the wrong hands. However, was it a part of a weapon, or was it something more sinister?
Turns out, it was neither. This is a cassette demagnetizer used mainly in the 1960s. Back then, cassette reels would become magnetized and have to have the electric charge taken out of them. As cassette technology improved, these things slowly faded away from existence. Now, it’s an antique item that would probably bring back happy memories for our grandparents.
