I have never tested adult diapers, but when I was a kid, I had Pampers tested on me. I had to lay on a glass table, while they stuck a tube in my diaper and pumped in a liquid. The people running the diaper test watched me to see if and where my diaper leaked. Mom was paid for the diaper tests with free Pampers. As a kid, I did not like the diaper tests. Anyone else have an experience like this?
