In my small experience, undergraduate research is like eating Raisin Bran cereal. There's a lot of stuff going on that's not that interesting. Cleaning and other routine tasks in the lab are like the flakes of bran that make up the substance of the experience. They can be tedious and flavorless.
Exciting moments of action and discovery are the raisins. A raisin brings flavor to a spoonful of bran flakes. Some spoonfuls have more raisins than others. Together, the flakes and raisins make for a hearty and wholesome bowl of cereal.
I haven't had much research experience yet, but I do know that I like eating Raisin Bran.
