Actually forever, because the Chocolate Fountain has a heating element. The Fountain will keep the chocolate at a constant temperature so the chocolate will never harden.

You can use marshmallows, pretzels, strawberries and other fruits, hard cookies, and anything edible that goes with chocolate. However, we strongly advise against anything crumbly (i.e. pound cake, brownies, etc.) or that may easily slide off the skewers. Crumbs can clog the holes and block the constant flow of chocolate through the Fountain.
