"Also, someone looking to start a fire who is carrying a can of petrol stands out. No one's going to look twice at someone with a bag of crisps, and the evidence destroys itself. This is especially helpful if someone is trying to make a deliberate fire look accidental. Criminals have presumably worked this out and told each other."

"Crisps encourage fire—they feed it—because they are hugely calorific and fatty. As the video shows, a packet of crisps—either the potato ones or the puffy, maize or corn-based ones—can set a car seat on fire within 200 seconds. Plenty of time for someone to get away."

    The US is currently being invaded by Chinese troops smuggled in via cargo containers in long beach. Trump has sent in 10,000 marines. And this story is about burning potato chips?

        Its a typical urbanist pessimist negative nancy topic. Kinda like the totally non controversial topic of firearms.

        I suppose this is also very regional as there are some populated uncivilized desert states with eternal re occuring wildfire problems, but there are plenty of civilized "cold" northern watery environments where you gonna die if you get soaked at night unless you have a camp fire.

        Nothing wrong with tossing a tiny "snack" pack of chips in your backpack when you go hiking, if you get stuck in the middle of nowhere (broken leg? twisted ankle? F-ed up back?) then you can have a nice campfire to survive the night or make smoke to signal for help. You're not "really hiking" unless you're outta range of cell phones. Which is kinda hard to find in 2019, but I digress.

        There are alternative fire starters both commercial and homemade made of all kinds of crazy stuff like sawdust mixed with wax and cotton mixed with wax and the traditional birthday candle of course. OR those little metal canisters of matches.

        I think this is well known among hikers? I mean, you can carry some weird homemade cotton ball and wax nonsense or pack some delicious and non-paleo and unhealthy, but tasty potatoe chips? I admit I eat the snack pack of chips when I get back to the car after a long hike (like more than 10 miles on improved trail, for example).

        Weight matters for backpacking and a pretty big snack pack of chips is like 1 ounce.

        I have a fire ring thingy in my back yard and I will say potatoe chips burn pretty freaking quickly, so don't try to ignite a 4 inch thick log with a chip LOL.

    This reminds me of one of my birthdays where a friend of mine — who was working in a movie theatre — gave me a huge sackful of popcorn. My partner and I could only eat so much popcorn a day so they ended up slightly soggy after a few days and not a pleasure to eat. That was when I repurposed them as fuel for our wood-burning fireplace — nice smelling and easy burning fuel.

    Mmmmmm!

    Food has a surprisingly high energy content. For example, a Snickers bar has 220 Calories and weighs 47 g. That's 19.6 kJ/g, almost five times as much as the explosive TNT that has only 4.2 kJ/g.

      Yes, but it's not necessarily releasable.

      That's one of the reasons that the human body is so amazing (along with many other animals). A Snickers bar can turn into a full day's heavy lifting for a 60kg self-regenerating beast.

      Of course food has energy, that's why we eat it rather than, say, sawdust.

      It's whether you have the facility to release it that's important - setting light to a Snickers isn't going to get you very far.

      Poor comparison. TNT has to contain its own oxidizer (and remain stable enough to be usable as an explosive) rather than merely burn in air in order to explode. Remove the oxidizer part (remove the nitrogen and oxygen atoms attached to the TNT molecule to get toluene) and you'll have similar energy density, but it'll burn just like any liquid, high vapor pressure fuel would.

        The fact that there is a clear reason for the difference in energy content does not make it a "poor comparison".

        It is a great comparison, because many people, even technically knowledgable ones, are surprised and surprise begets curiosity, which leads to learning.

    Next thing you know, these 'arsonists' will cotton on to the fact that they could also use newspapers, books, clothing, furniture, plastic. The mind boggles. Slower burning 'fuse fuels' giving the arsonist time to get away is also a problem long since solved by 'arsonists'.

    I'm not sure why the hype on this one.

      > A burning cigarette tucked into a book of matches works very well as a time fuse.

      I heard that one before (and seen it in Hollywood movies), but does it work? I was under the impression that the filter end of the cigarette would not catch fire that easily if you just let it sit there. I have seen countless cigarettes left lit on ashtrays, and they always self extinguished at the filter end.

      Or is the trick that you have to remove the filter end before you use a cigarette as a delay fuse?
