alt Hacker NewsI discovered a (lame) party trick some microwave ovens are capable of.
Many microwaves will let you set the power to 0% by pressing the power button then 0 or 00.
You can then put a cup of hot water from a kettle or the hot water tap in the microwave on 0% power for two minutes and it will come out colder.
Bonus points if you have a thermometer at hand.
TIL microwaves can double as a Blow Air Across It machine.
If one person in the house can't tolerate very hot foods, it could be useful for eg cooling off grandma's bowl of soup so she doesn't need to wait.
