The Stuff You Should Know podcast is full of awesome trivia, but one of their recent episodes taught me a lot about a subject I thought I already knew well. The title is “Sunburn, Suntans and Sunscreen“. Throughout the episode they busted a bunch of myths that I thought were facts and explained the science behind sunscreen. I’m especially interested in the topic given the three chunks of skin that I’ve had cut out of me. If you only listen to one episode of that show, this is a good one to listen to! You don’t have to do anything fancy to subscribe if you don’t want to. Just go to that link and click play.

And if you like that one, check out another one of my recent favorites: How Ketchup Works.

Amazing Live Streams

The other morning I stumbled across the NASA live stream and they were doing a space walk. I threw the video onto the TV and Elijah and I watched live video of someone in space. Then later at work I read the day’s xkcd comic and it referenced a live video stream from a robot that is exploring the ocean. The future is now!

Lots o’ Legos

In on of my recent Best of YouTube posts, I mentioned a user named JANGBRICKS, but I think he deserves his own post. His real name is Bamidele, but he goes by the name JANG which stands for “Just a Nice Guy.”

Elijah likes to watch his Lego videos, but he has lots of other collections like Playmobil, Halo stuff, and knives. I don’t know where all his money comes from, but he worked for PayPal and EduSoft in the past.

Regardless of how he does it, his Lego collection is enormous. In a recent video, he mentioned that he has about 500,000 pieces that came from buying Lego setes and a couple tens of thousands more from custom orders. If you figure an average price of $0.10/piece, that’s a big investment, but honestly, it’s not as much as I thought when I saw his setup.

On his YouTube channel, he reviews all (?) the new Lego sets and he also shows custom builds that he does for his big city. He states many places that Lego does not sponsor him at all and everything is bought with his own money. His custom builds are a treat to watch. He’s a magician with Legos.

If you enjoy Legos, this is a great channel to subscribe to.

This first video is actually two videos. Sneaky. The one embedded below is a series of physics riddles. Watch it first and think about your answers. Once you feel good about your answers, what this video to see the actual answers. I only got two right (and one was little more than a lucky guess.)

Mark Rober is the world’s most awesome uncle and he’s done it again with an awesome Hot Wheels video. Elijah loves his Hot Wheels track and I want to show this to him, but I don’t think he’ll understand that it’s not totally real. He’ll spend the next month asking me for enough track to fill up our whole house.

And finally, I’ve never thought about how ravioli noodles are made, but now that I’ve seen it done, it seems like it could be a fun project. I’ll add this to the list of things to build if I ever get a lathe.

Destin over at Smarter Every Day posted a great video with a guy who can talk backwards. They test him to see how different activities affect his ability to talk backwards. Destin is also the co-host of a good new podcast called No Dumb Questions.

This next recommendation is really an entire channel: The Q. These videos show how to make some fun machines with common household items. His main materials are cardboard and hot glue. For example, here’s a robotic arm made from simple syringes and cardboard.

How many do think are in Australia herding cattle with a HELICOPTER? 10? Well, according to this article, 10 of them die every year. This looks very effective… and completely crazy.
