How Much is Inside Granola Bars?

Granola bars. At first glance, they might seem like of sturdy logs of oats, peanuts and dried apple bits, scraped from the floor of some dusty hippy factory.

Although this box looked like enough granola to satisfy an entire drum circle, granola bars are infamous for the being over-packaged. Sean, Brooke and I wondered, how much granola is inside a box of granola bars? 

On Friday night, we decided to find out. 


We had selected a box of Nature Valley Chewy Trail Mix Bars. This brand had the fewest roots and twigs. In fact, this was the recipe used as the trail for the Wonka factory park.

The 7.4 ounce box was $3.99.

The first thing to do was to measure the box. It was 6 1/2 inches wide, 5 5/8ths inches tall, and 1 3/4 inches deep, totaling 64 cubic inches.

Lounging inside, there were six bars, individually wrapped.

The box also contained a generous serving of fresh air.

Brooke had an idea to test the actual packing limits of the box.

We loaded our box to see what it would hold if it was really full...ten bars!

One by one, we unwrapped them.

Stripped of their shiny Mylar wrappers, the bars seemed... small.




We lumped all six of them into a solid block for easy measuring. Now we could determine how much of the box had actually been occupied by granola, and how much had been lies!
