Whats that smell?

The other night Daniel and I came home and after ten minutes of being home we could smell something burning. We go in the kitchen and we looked couldn't find where it was coming from so we thought it was the candle that was on the burner. After a few second turning that off we could still smell it. We go back in the kitchen and the towel on the toaster was on fire. Daniel hurried and grabbed the towel and put it in the sink. Our cute blue towel was all black. It was sad throwing it away. On the towel was some bread and the bag started on fire too. Here are the pictures of the bread but no pictures of the towel. Daniel threw it away before i could take a picture.
