It could be a new YouTube Channel.
That would be awesome! You could try different calibers and compare the cheap CCP products with American and European brands. I'm thinking you could start with an Instant Pot and compare it with an American-made crock pot from the 70's (should be able to pick up some old ones at a thrift store).
The possibilities are endless!
