While stored in a dark and cool environment, Mexican jumping beans will remain dormant. When the jumping beans are exposed to warmth (such as the warmth from your hands) they will begin to jump. When not playing with your Mexican jumping beans, or when you would like them to be quiet, they may be stored in your refrigerator -- where they will remain dormant.
Once every couple weeks, spray your Mexican jumping beans with some water to give them a drink. Allow the water to soak in; then dry off your Mexican jumping beans.
Mexican Jumping Beans Can Remain Active And Jumping For 8 Months, Or Longer!
Never freeze your Mexican jumping beans. Jumping beans can be sent in the mail, just be careful if you are sending them to a place where temperatures may be below freezing. Do not let them sit in a mailbox exposed to freezing temperatures. If Mexican jumping beans are accidentally eaten (by a person, cat, or dog!) -- they are probably not very tasty; but not harmful.
