We wanted to get an idea if being flammable was only a property of Cheetos, so we tried burning several other types of chips.
We started by burning Cheetos Puffs.
We burned Fritos.
We even burned Doritos - about all of the "itos" we could find.
We had a few observations.
1. While all of the chips burned well, the Doritos burned the best. We think this is because the chips are bigger, and there is a greater surface area to mass ratio.
2. The Crispy Cheetos were the hardest to light on fire. They have the lowest surface area to mass ratio of the chips we burned.
3. There was a yellowish liquid that dripped from all of the chips except the Cheetos Puffs. We weren't sure what it was until we washed cookie sheet we were using as a fire pan, and discovered it to be oil. We think the fire melted the oil, and it was able to drop out of the chip before the fire consumed it.
