In the name of Science, on Sunday kid #1 and I tested six popular, salty, crispy snack foods in order to determine which make the best material for lighting fires. We approached our experiment with a few hypotheses, and were surprised by some of our results.

Four of the snacks we used came in 1 oz (28.3 grams) packages. The Smartfood popcorn and Fried Pork Rinds came in larger bags; we approximated serving size by transferring small portions into emptied snack bags. We used the nutritional information provided to collect information about calories per portion.
WARNINGS: Do not attempt to set these snacks on fire unless you are in a reasonably safe, well ventilated environment and have responsible, sober adult supervision. ALSO: No one should actually eat these snack ‘foods’ unless you wish to become bloated and unhealthy.
Conditions: sunny, dry, light breeze, temperature about 50 degrees Fahrenheit.
Test equipment:
1 foil pan
2 small boxes kitchen matches
1 digital wristwatch (more on this later)
1 digital camera
1 notebook
1 pen
(1 cell phone)
Test subjects:
Lays Classic Chips (2 x 1 ounce bags)
Doritos (2 bags)
Fritos (2 bags)
Cheetos (2 bags)
Smartfood popcorn (1 large bag)
Fried Pork Rinds (brand unknown, purchased at Smith’s, large bag)
Method:
One serving of each snack “food” was placed into the foil pan. We then attempted to ignite it.
We took the following measurements:
Time required to ignite
Where applicable, number of tries it took to ignite
Length of time for the entire serving to burn (defined as, serving appears completely consumed and no flames are visible)
We also took the following qualitative notes:
Intensity of flames
Quality of smoke
Miscellaneous notes
We tested each snack twice.
In those cases where the materials failed to ignite. we made sure there was no flame and then dumped the waste. In cases where the materials ignited, we buried the waste in sand.
After about seven years of use, my digital watch’s battery expired just as we were preparing the first run. Luckily, my cell phone turned out to have a Stopwatch function. When did they put that on there? I never remembered seeing it before. It proved invaluable, but that doesn’t reduce my unease at Sprint putting stuff on my cell phone without my knowing it.
Results:
Most snack ‘foods’ did ignite, did burn, and emitted awful-smelling smoke as well as a revolting brownish-black grease. We had a few surprises, and are able to make some firm recommendations for specific firestarting needs.
1. Always prefer popcorn! The Smartfood was the runaway winner. It ignited the fastest–an average of 6.5 seconds–and burned intensely, though not for very long.
2. Pork rinds: mega-disappointment! Your hardy investigators both felt these would burn the best. We couldn’t have been more wrong! They completely failed to ignite on both runs. Pork rinds are stupid.
3. Doritos came in second in terms of being a useful firestarter. They lit in an average of 8 seconds and burned for at least 7 minutes, accompanied by a loud hissing noise and volumes of thick, putrid smoke. Their shape proved very conducive to building nice little flammable piles.



4. Lay’s potato chips, while not as outright bad as pork rinds, are also much more flame-retardant than we expected. They did light, but never held a flame and always self-extinguished in under 3 seconds. Lay’s are useless as a firestarter.
5. Fritos and Cheetos both lit slowly (15 seconds average of Fritos, 17.5 seconds average for the Cheetos) but burned strongly and well. Their flames were tall and hot, and their smoke only somewhat putrid. If popcorn isn’t available, either would make a good choice, especially in damp conditions when your kindling might need longer to ignite. One batch of Fritos was clocked at 9:08 burn time–which we felt remarkable for one ounce of snack ‘food.’
6. I anticipated a positive correlation between the calories contained in each serving and the burn time, but the best burner (Smartfood) and the worst (pork) both had 160 calories per serving. Go figure.
Conclusions: buy Smartfood as a firestarter. Don’t eat it, obviously. Pork rinds have no reason to exist.
Ideas for further research:
The two obvious candidates for further research are: popcorn, to determine which brand will burn the best; and pork rinds, to determine if they are in fact flammable at all under normal conditions. Doritos also merit further investigation to determine if there is a difference between the various appalling flavors available.
Also, some pointers for your own research into the subject: if possible, burn your materials over a fine grating of some kind which will permit the disgusting oils to drain away. Next, stay out of the wind as much as you can. It’s better for the science part of it, and your clothes and hair will be MUCH much more appealing afterwards.
Finally, for heaven’s sake, don’t eat your leftover materials, or feed them to any pets you love! Instead, burn them all.
