Spider-Man’s Silk-Producing Breakfast Revealed

1

While watching the 2002 Spider-Man film, Mark Lorch’s mind wandered from the plot and began focusing on what kind of breakfast Spidey would have to consume to spend the day shooting silk. Naturally.

The process began with determining the strength of his material and the force applied to it before moving on to the amount of protein that would have to be consumed to fuel the production process. As his benchmark, Lorch chose the European garden spider, whose silk is similar to piano wire, and calculated a force of 735 Newtons for a weight of 165lbs. In order to produce 100 yards of this silk, Peter Parker would have to down 15 eggs for breakfast. However, as Lorch then pointed out on The Conversation

“spider silk consists predominantly of a protein call fibroin. Proteins are made from different amino acids, and fibroin is about 42% glycine. While egg consists of just 10.7% glycine and serine (I’m counting serine because it can be easily converted to glycine). So really Spidey needs to consume four times more egg protein than the silk protein he plans to use. So actually he needs 60 eggs for his 100m of silk.”

This is further complicated if he wants to swing around with MJ, as that feat that would require about 900 eggs.

The moral of this story? Never follow Spider-Man into a bathroom.
