You'd think hitting the defrost button in your car on a chilly morning would be the quickest way to defrost your windshield. But not necessarily so, according to ex-Nasa engineer Mark Rober, who has come up with a way to defrost car windows in half the normal time. In his video, he explains how to speed-defrost our car windows, along with a peppy science lesson that backs his method. In a nutshell, here are the four steps:
1. Blast the heater
2. Blast the AC
3. Turn OFF the air circulation
4. Crack open the windows a bit.
He also offers tips that involve cat litter and shaving cream so that you, too, can become a defrosting ninja. Thanks Gizmodo!
