You're viewing part of a thread.
It's not the size of the space that enables the chips to move at speed. So no, I don't believe you have studied any science. Watching sci fi movies doesn't count.
Here's a practical example for you to try. Make sure you get your parent's permission!
Take a sandwich bag and put ten corn chips in it. Remove as much air as you can and seal it. Now, shake vigorously. You'll find that the chips are held almost motionless by the plastic and thus do not break.
Now add a little air to the bag. The chips can now move. As you shake the bag back and forth, they collide, rotate in the allowed space, reposition inside the bag. You'll get a few broken chips.
Now add heaps of air to the bag. When you shake vigorously, the chips all move in different directions, pin wheeling, bouncing off the bag surface, rebounding into each other, rotating inside the bag to present their crisp faces to the hardend edges of other fast moving chips. You'll notice that it's not the moving of the bag that damages the chips. It's the sharp and abrupt change in inertia. The extra air allows the chips more space to orient in dangerous ways before the change in inertia smashes all the chips together at one end of the bag.
Now that you've done the fun practical part of the lesson today, I'll follow it up with a simple thought experiment. What brands do you think have more broken chips in them?
The brand with the most broken chips is Tostitos, which packs their chips with very little air. And they're usually really broken.
Doritos in my experience is the second worst for broken chips, and they too also use very little air, just a bit more than Tostitos.
The brand I find with the fewest broken chips is Lays, with lots of air.
Wonder why do you?
Try this experiment. Instead of just shaking your chip bags vigorously (something that is highly unlikely to happen in real life). Put your chips in a box full of tons of other bags of chips, and toss those boxes around a warehouse. You will find the bags with less air will generally have more broken chips.
Now stop being a condescending cunt, it's rather unbecoming of you.
Unfortunately, you've missed the point of my experiment, re earning my condescension. I'm demonstrating the terrible effect of air as a cushion against force. I'm not replicating shipping at all.
It's also quite revealing that the brands you named are substantially different in manufacturing process, resulting chips with significant difference in tensile strength and edge thickness. Those figures are far more relevant to broken chips than air.
So here's your next training course in chip packaging. Take ten chips and drop them onto various surfaces from waist height. Drop them vertically and horizontally. Then put individual chips on bags with varying amounts of air and replicate. Then multiple chips. Have your parents help you write up the results and share with all your {online} friends!
Nah, you're just a stupid teen trying to sound smart. And if you are an adult then bye goodness do I feel bad for your immaturity.
Have fun with that, but your ideas are stupid because more air does protect the chips from the actual forces and stresses they will experience while being shipped. None of your hypothetical scenarios are even close to the real world in terms of the forces and stresses experienced.
I don't have a condescending word for the kind of person who believes more = better without comprehending the basic concept of reality. Thankfully, I don't need one as Darwinism ensures there aren't many of you around.
Well published doctors with PhDs in Chemistry and over a decade of academic experience? You're right, there aren't a lot of us around.
Ooh internet credentials! So awesome. And an unrelated field? Mmm very intimidated I'm sure. You're an idiot if you don't recognise the shrinkflation. Regardless of your claims.
Never said their wasn't any shrinkflation, way to completely change the subject. And chips are sold by weight, not bag size, just read the bag and you'll know exactly how much you're getting.
The addition of more and more air has nothing to do with chip protection. It is shrinkflation. That has always been my point, regardless of whatever you've mistaken it for.
And you're a magical level of dumb shit if you don't see they are reducing weight and increasing the air to make bags appear more full. "Protects the chips" and "Weight not volume" are the literal marketing campaigns designed to cover up the shrinkflation. Which, since you read the order of amount of air per brand articles, varies from 17%-73% with ckearly no regard for the optimal chip protection amount and quite obviously "as much as we can get away with" amount.
As I've repeatedly said, you're whiny disagreement is more about you than this actual situation in the market in the real world.
Nope, the chip bags with more air have less broken chips, which makes me happy. I'm smart enough to actually read the bag and know how much I'm getting. Given everything is either inflating or shinkflating, that argument is pointless. Nothing is staying the same price, and I see no need to cry about it.
You being a condescending teen, makes your hilarious attempts at a debate rather quaint and amusing.
A debate requires two reasonable points. Your dull comments lack a point. With no need to cry about it, why do you have the need to comment on it? Just keep on buying more air and thinking you are winning at life. The rest of us can enjoy the laugh.
