A charred, cut open energy drink can, stuffed with what looks like burnt wax paper. What could this be for?
Found on the floor of my garage. It wasn't there earlier in the day. For context, I current look after my 16-year-old nephew, and it's almost certainly from him. He's currently sleeping, and I do intend to ask him about it tomorrow, but I want to have a sense of what it might be before I bring it up.
It may just be the product of a bored teenager setting something on fire to see what happens, and since he's a Boy Scout, I was considering that it might just be some kind of improvised DIY firestarter for camping or something.
EDIT: A few people mentioned that the stuff inside is possibly/probably the internal lining of the can.
Also, I checked it again, and it doesn't smell like much of anything but aluminum. Even the scorched bits just smell metallic.
