A request by Carter F! Carter sent me several requests, but I'll need some time to get to them. The one that I thought was new and unique was to microwave credit cards. Well, I was hoping it would be more spectacular, but ultimately, the only thing that happened was the security hologram gave a quick spark and that was about it. You can barely see any action in the video, so I decided just to post the "after" picture. The magnetic strip on the back was unaffected.
Thanks too to Ian N who offered to send one of his used gift cards!
