Hi alert800,

Welcome to the forum. It sounds like this project would use the engineering process rather than the scientific method, so you might find this helpful to read:

Whether that's "good" depends on the requirements for your science fair or class project. You can get an idea of what similar devices are on the market by putting "electric mortar and pestle" into a search engine (and you'll get better results if you're careful with the spelling).
