Eh, just do what most microwaves recommend for heating liquid: put a tea spoon in there. And if you are thinking "OMFG that will explode", read about microwave and metal myths ;)
Yeah, or aluminum, or knifes with the edge exposed. Essentially metal pieces close together, or sharp edges, both create sparks. Unless you have murder spoons, you are fine, I always put them in when I heat liquid, and the manual even says to do so.

Metal forks are the problem. Sparking occurs between the sharp tips. Supposedly spoons are safe, but I don't have any first-hand experience with this.
