I'd count out little dixie cups of 100 popcorn kernels each. Then I would weigh them and put them all in the laundry room, where the humidity was pretty constant for different time periods over a few months. I took another set of batches and heated them up in the oven for different periods of time. Then re-weigh to see how much moisture was lost from the kernels. Seeing that the amount of unpopped kernels and volume was pretty consistent between the fast drying and slow drying allowed me to predict what it might be like for years old popcorn by really drying out the kernels. I also did some batches in a high humidity environment using a box with a humidifier and seeing the weight gain from the moisture.
Everything was popped in an air popper to give everything that was going to pop the time to pop. Then count the unpopped kernels!
The overall conclusion is popcorn is probably good for up to a year, and you can do a lot better than the microwave bags if you buy loose popcorn. Generally more moisture helped, but there was a sweet spot range where there's enough moisture to have the steam make it pop big and open, but too much humidity made the casing soft and it would have just a kernel that was cracked but didn't pop.
The hardest part was coming up with a precision scale that could do two digits of precision. Basically everyone that used them then were either drug dealers or people who bought actual lab equipment.
Thank you for coming to my popcorn ted talk.
Oh and I forgot, this was when I was in 5th grade. Good times.
