My mom found a tiny plastic vial that looks like something used in a lab. It is about one inch long with a cone on the end. On the opposite end is a metal cap that looks like one you would find on an insulin bottle. However the vial itself is only about half a centimeter in diameter. Inside are tiny white smooth spheres about 8-10 of them. I was wondering what this thing is and what its used for? any ideas?

If you could give me an explanation, that would be great. Perhaps some laws or principles that I could follow for an upcoming exam? I don't quite understand the relationship between Watts and Calories in the mathematical/theoretical sense.
