Nachos are delicious. And versatile because today they re also going to help us learn a thing or two about your digestive system. Nachos can provide us with energy and raw materials, by first ingesting something nutritious, propelling it through the alimentary canal where it will be mechanically broken down, and chemically digested by enzymes until my cells can absorb their monomers and use them to make whatever they need. And eventually, there will be pooping. Pssst... we made flashcards to help you review the content in this episode! Find them on the free Crash Course App!

Heading to London for just a few days it was a pleasant surprise for us to attend Blogstock 2015 hosted in beautiful Aldenham Country Park. As the world s first blogging festival creative minds converged to learn, share, network and party. We were fortunate enough to catch up with old friends and meet up with people we ve known for years online face to face for the first time. We also had the opportunity to speak on a couple of panels related to YouTube and other video publishing platforms. Overall, it was a great event and next time we ll bring our tents to enjoy the entire three day experience.

It is called Blogstock. And as you can guess from the name it is a blogging festival. So we re just heading over there. It is taking place in a park just north of London. And yeah, the weather isn t really cooperating but hopefully it ll get sunnier later on in the day. Alright, so we ve arrived at Blog Stock. I ve had my hot cacao so I m all warmed up. And now we re going to give you a little tour of the place. What are your sort of like top tips for a startup Youtuber? Okay, my top tip would probably have to do with SEO. I see a lot of people who don t write a proper title for their video. They don t include any tags. They don t have a description. And you have don t have the audience on your channel yet and you want people to start finding you your video needs to rank when they re searching for the best beaches in Thailand. Or you know, the best restaurants in New York City. So do really good SEO on your videos so that you ll show up in the searches, people will find your channel and maybe if they like what they see they ll end up subscribing. So good SEO can help grow your audience. Even though SEO is kind of boring and some don t want to learn about it. Your favorite thing about Blogstock? If I had to narrow it down to just one favorite thing it was networking with other bloggers and brands in the same industry as us. There is so many creative people doing amazing things. It is great to get to know them as individuals and to see what they re doing in terms of projects. And what was your most memorable experience from blogstock? I think getting to talk about YouTube and video just because it is something I really enjoy and I wish more people would try making YouTube videos. So that was a lot of fun. Paul, so tell us why should people come to blogstock? If you re a blogger you should come to blogstock because there is lots of different sessions from different niches where you can learn all about blogging obviously. Instagram, photography. You can learn about how to make money from your blog. How to be more professional. How to pitch. All sorts of different sessions. We also have lots of varied sessions so some stuff is more inspirational as well. Like how to conquer your fears and live life to the full. That kind of stuff. And we have some great food. Some wood-fire pizza. A great bar. Also craft beer and lots of different things going on. We ve got fancy castle going on, lots of fun games. Yeah, it s great so come along, camp for the weekend and it is loads of fun. This is part of our Travel in England series. We re making a series of videos showcasing English culture, English arts, English foods, English religion, English cuisine and English people.

This Copper Bike Rack is made from copper pipe fittings and a small piece of felt. I used an angle grinder to make two cuts along a 2" to 3/4" reducer T fitting. I soldered the cut T-fitting to a length of 3/4" copper pipe and then used a nut and bolt to connect the other end of the pipe to a 3/4" T-fitting.

Sea otters are a keystone species, meaning that an entire ecosystem depends on their presence. After they were nearly hunted to extinction for their dense fur, sea urchins (the otters favorite food) nearly destroyed the Pacific kelp forests, a habitat that hundreds of species rely on for food and shelter. Thanks to the hard work of conservation scientists at places like the Monterey Bay Aquarium, sea otter populations are on their way back. Here s the story of one orphaned sea otter pup s journey back to the wild Why are we in Monterey? PBS and BBC are teaming up to bring you an incredible LIVE nature broadcast direct from Monterey Bay, California called BIG BLUE LIVE. In late summer, thousands and thousands of ocean animals come together here, in one of the richest ecosystems on Earth.
