It’s chilly out there, but it is still a good time to discover science, say by throwing boiling water in the Arctic-cold air to watch it freeze in mid-air. Another way to pass the time might be attempting to tickle oneself or discovering that there’s Antireflection (AR) coatings for plastics in the works. That and more in this week’s Tech News 4 Kids newsletter! Join our classes to learn all about these amazing technologies — artificial intelligence, coding, and more.

Reaching the Boiling Point




Feeling bored in the cold? Well, some people have found creative ways to entertained while they wait it out, one of them being a beautiful science experiment — throwing boiling water into the air and watching it turn to snow. But how does it work? Find out the science behind the photo-worthy moment here!

New Findings on Why It Is Hard to Tickle Yourself

We’ve all tried to do it — tickle ourselves. But it yields to be a much more difficult task than expected. It’s been suspected that the lack of surprise is a big factor, but a recent study shows that there might be more at play. Find out why you can’t really tickle yourself here!

Plastic is already pretty transparent, if it’s clean of course. However, new antireflection (AR) coating might take one step further, to make plastic almost invisible. But how are they doing it? Find some clarity about AR here!
