How to make soft serve ice cream at home #DIY #CraftersU #Cooking

Chris Young, co-founder of ChefSteps and co-author of Modernist Cuisine, shows us a hack for making soft serve ice cream at home with dry ice.

Make your own snow crystals!

Snowflakes may not be a functional thing, but they are definitely beautiful. But instead of trying to catch them out in the wild, why not grow them yourself? In this video from SciFri, Ken Libbrecht, Caltech physicist and author of “The Secret Life of a Snowflake” tells us exactly how you can do this for only a couple of bucks! Now that’s some cool science! (Pun intended)

What is cryogenic manufacturing?

Have you ever wanted o make something out of rubber? Not just a smooth ball, but something complex? Sure, 3D printers can print soft objects today, but they are very limited. Wouldn’t it be great if you could take any rubber material and just mill or lathe it? Well…you can! You might have seen scientific demonstrations of how hard and brittle things can get when deeply frozen? Leave it up to our scientific favorite Applied Science to test it out and see how it might work. You might even be able to make your own specially designed rubber parts with nothing more then an mill and some dry ice!


The incredible science of acoustic levitation

This is truly an revolutionary video! Did you know that objects can be levitated and moved around in mid air, using only sound? In this incredible video from Yoichi Ochiai (YouTube Channel 落合陽一) we see the first successful attempts to acoustically levitate small objects like styrofoam balls, water droplets, matches and even metallic nuts! Perhaps one day we can even levitate big objects like skateboards or cars? What would you like to levitate with this technology?
