Jumping across it is fun, but for real fun, take it out and put it in the freezer, with your ohm meter connected across it and showing an open circuit. While your wife growls at you for standing in front of the open freezer like an idiot, ignore her as we always do and watch the ohm meter. Once the snap disc cools to about 40*F, it closes and the ohm meter shows 0 ohms, proving that the snap disc is good. Soooo fun.
