Quatity_Control,

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?
