It is possible for the Ice to partially melt and the coin to not sink, the ice would need to COMPLETELY melt before this test would work, given the nature of ice it is possible for food to raise to an unsafe temperature while the ice is still melting
This "trick" should not be used in place of proper temperature monitoring
- Retric 6y agoTrue, but easily solved by adding salt to the cup. At -20c salt is completely ineffective, but the cup will melt long before reaching 0c.
