  Sometimes we won’t know the exact details of the samples as the companies who send them in want to keep it a secret! But we’ll usually know what kind of material we’re looking. I’ve seen so many new things since I started my job though. For example, I’ve found out about how computers work and what mayonnaise is made of!
