Tear Jar

We found that when toddlers begin pitching a temper tantrum, a distraction was a good tool to calm them down. I took a Mason jar and labeled it with my toddler's name and kept it in the kitchen. Whenever the tears would star flowing, I'd run to the kitchen and get her "tear jar" to catch all her tears. 

The novelty and the idea of catching their tears usually, at least in the beginning, is enough to turn the tantrum around. The idea is that you hold the jar up to their eyes to collect their tears. This usually gets them more interested in what you're doing and less interested in their tantrum.
