A microwave beverage and food preparation apparatus that, in one embodiment, converts a common fluid vessel such as a cup, mug, or bowl into a whistling kettle. A user places a lid having an alarm on a vessel containing liquid to be heated in a microwave. A member made of, or containing, nucleation-site-rich material on the underside of the lid extends into the liquid to activate boiling, thereby assuring a safe transition of the liquid to a normal boiling state. Steam escapes through an integrated whistle in the lid, alerting the user to the boiling.

The invention claimed is: 1. A food preparation apparatus, comprising: a lid having an upper side and a lower side; a whistle alarm attached to the lid; and a boiling activator attached to the lid and extendable beneath the lower side of the lid, the activator comprising a stem pivotally connected to the lower side of the lid. 2. The apparatus of claim 1, wherein the stem is formed from a material relatively rich in nucleation sites. 3. The apparatus of claim 1, further comprising a material attached to the stem, the material being relatively rich in nucleation sites. 4. The apparatus of claim 1, wherein the stem is pivotable between a first position adjacent the lower side of the lid and a second position extending away from the lower side of the lid, and further wherein the lid is capable of resting substantially flat on a flat surface when the stem is in the first position. 5. The apparatus of claim 4, wherein the pivotal connection of the stem is such that when the lid is in an upright position and no external force urges the stem toward the lower side of the lid, the stem is in the second position. 6. The apparatus of claim 1, wherein the whistle comprises a chambered whistle. 7. The apparatus of claim 1, further comprising one or more ridges protruding from the lower side of the lid, the one or more ridges being configured to secure the lid to a cup. 8. The apparatus of claim 1, further comprising a gasket attached to the lower side of the lid. 9. The apparatus of claim 1, further comprising a weight secured to lid. 10. The apparatus of claim 1, further comprising a cup, the lid being removably placed atop the cup. 11. A food preparation apparatus, comprising: a lid having an upper side and a lower side; a whistle attached to the lid; and a boiling activator attached to the lid and extendable beneath the lower side of the lid, the activator comprising a flexible extension member having a first end and a second end, the first end attached to the lid and the second end attached to a sinker, the sinker having a specific gravity greater than that of water. 12. The apparatus of claim 11, wherein the sinker is formed from a material relatively rich in nucleation sites. 13. The apparatus of claim 11, further comprising a material attached to the sinker, the material being relatively rich in nucleation sites. 14. The apparatus of claim 11, wherein the lid forms a seal between the lid and the cup so that when steam is generated by a liquid heated within the cup, the steam escapes through the whistle, causing the whistle to emit an audible noise.
