- Due to applied pressure, the melting point of ice is lowered below 0 °C. As a result, ice gets converted into water at 0 °C.
- When the applied pressure is removed, the melting point is restored to 0 °C and water gets re-converted into ice.
- Preparation of ice balls uses phenomenon of regelation. The shredded ice is pressurised around the tip of the stick and then due to regelation gets re-freezed in the form of a single solid ice ball.
