As Skeptics we're not very fond of scammers, and we often try to protect the public from those who would rip them off with dodgy devices and ineffective products. The video below documents a feat of engineering, a device that targets the problem in the US of people who steal people's parcels - and it targets them in a pretty funny way. Although theft is not really a scam, it's still enjoyable to see unethical people get their comeuppance - and it's mentioned later on in the video that this device has also recently been used against scammers. And to be honest, I needed a good excuse to share this video!
