696 How To Defrost Your Windscreen With Science
Or else you could end up like this... Matthew Bové/WKBW via Twitter

Leaving a car parked outside during the cold winter nights could lead to a frosty windscreen, if not worse, like this poor guy found out.

So, if you don’t want to waste energy using a scraper or waste time with that defroster heating up your windscreen, then science has got a quick and cheap solution for you.


The solution is an actual chemistry solution, a mixture of one part water and two parts rubbing alcohol that will dissolve the frost from the windshield rapidly and effortlessly. Isopropyl (rubbing) alcohol has a freezing point of -89°C (-128°F) so the solution not only doesn't freeze, it actually helps to lower the freezing point of water and melts the frost away.

Check out the video below to see it in action.
