When I was a kid, I loved to play with little Mattel Matchbox cars by sending them down their orange tracks, but it turns out the real fun is dousing them with butane and photographing their fiery demises. My husband handled the pyrotechnics, and I just clicked the shutter. (Let's be careful out there, people!)
I set up this photo for an "orange and blue" macro challenge (on Flickr). For that challenge, I'll need to feature a photo with a tighter crop, but I couldn't bear to crop out these flames here.
