Dry ice vs. soap 

I’m sure we all still fondly remember sitting in our high school science classes, marvelling at how cool liquid nitrogen is. I mean, it freezes anything in seconds – what’s cooler than that? You’ll be surprised – in this week’s video selection we take a look at some of the even cooler things that you can do with liquid nitrogen!

Make sure you watch the last video too because it will explain how all the things in the other videos work.
