Did you ever imagine just how much ‘air’ is in a bag of chips? Using the water displacement method, Kitchen Cabinet Kings measured the percent of air per bag of chips for 14 different brands of chips.
The overall average across the 14 brands was 43% but each there was a variation of 19% to 59%.
We filled up a bucket of water, submerged the bag of chips and marked the water level. We then emptied the chips into a plastic bag and vacuum sealed the contents, submerged the bag, and measured the change in water level. The difference was measured and numbers crunched to provide, you, the reader, with an easy to read percentage. We considered the fact that no two bags of chips are exactly alike, so we tested this twice per brand with the same size bag of chips. To ensure accuracy the starting water level was kept the same over the course of the experiment and an average was taken between the two percentages per brand.
