The entire experiment was to take place in the space of one hour, and we predicted that, while the subject's mouth might be a little sore after 75 Pringles, there probably wouldn't be any lasting damage ... at least, to to his mouth. (The calories were another story. More on that later). Much to our surprise, we discovered that we were wrong! The test subject was in fact unable to eat more than 50-60 salt & vinegar Pringles before complaining vehemently that his mouth was burning up. His mouth was in fact so sore that even after half an hour (still without water) he was unable (or unwilling) to consume a single additional chip. But wait ... it gets worse! A close examination of the subject's lips showed that in fact there was damage to the skin very similar to a mild burn ... of the sort you might get by sipping a scalding cup of coffee, or getting some really hot filling in a 'pizza pocket'-type food item. Moreover, over the course of the next two days, the subject's lips remained sore, and began to peel as if after a burn. We concluded that whatever the ingredients are that are in these chips, they actually do cause damage to the skin of the mouth, if they are consumed in a concentrated form ... consistent with a chemical burn. We paid off the subject with several chocolate bars, hoping he wouldn't sue us, and decided to learn something about the chemicals in salt & vinegar Pringles. The first thing we did was look at the list of ingredients on the side of the tube. Our next step, then, was to obtain some pH-testing strips, and do a little measuring.
