Anti-milk-lift

This glass circle is more clever than it looks.

How to use:

- Place it at the bottom of the saucepan in which you want to boil milk.
- Turn on the heat.
- When the temperature reaches a certain height, air bubbles will form at the bottom of the container.
- The anti-milk maker will start to "dance", rattling around in the saucepan. This noise will let you know when to turn off the heat before the milk rises.

This product is hygienic and heat-resistant.
