HIC 3" Stainless Steel Boil Alert Disc - Rattles When Liquid Boils & Prevents Boiling Over

HIC Kitchen's Boil Alert emits an audible rattle when liquids begin to bubble. Hear when pots begin to boil before mess even occurs. Plain water doesn't normally boil over. However, adding fats, starches, and other substances increases the viscosity of liquid which forms a film on the surface. When liquids heat and bubbles form and push up, they become trapped under that film and cause the pot to boil over. HIC's Boil Alert emits an audible rattle when bubbles collect underneath to signal when heat should be lowered. Simply place the boil-over preventer on the bottom of the pot and go about other tasks. Spend less time watching the pot or cleaning the stove. Works in any type of liquid and measures 3-inches in diameter to fit most pot sizes. Ideal for boiling pasta water, soup stock, milk for desserts, and more. Made from 18/8 stainless steel, it's heat safe to 1,472-degrees Fahrenheit and will never crack, corrode, rust, or react with food. Allow to cool completely before handling. It's dishwasher safe for easy cleanup.
