Measuring human digestive efficiency vs. a flame

 "200 Calories" on a nutrition label doesn't describe the total flammable caloric content. I explore the differences between digestible and flammable calories using a homemade calorimeter with glass windows.

Prototyping with Applied Science: Design and build a bite sensor




Join me in brainstorming and building a bite force sensor that allows paraplegic musicians to smoothly control an expression pedal. This video will include construction tips and tricks, methods, material selection, and a little design philosophy.
