Did you know that every year, about 14,600 ships pass through the Panama Canal? The canal is the most important waterway on Earth as it brings the United States closer to both Europe and Asia and connects the Pacific Ocean to the Atlantic. It’s, therefore, essential for the shipping industry. But how does the Panama Canal work? In order to enter the canal, ships approach from the sea, then several tugboats attach a towline to incoming cargo ships and move them into alignment with the canal locks’ narrow entrance. Once a cargo ship is firmly within a lock, a tugboat stays behind to make sure it does not move. The lock gate behind it then closes. Meanwhile, the lock gate ahead gradually opens, displacing water at a steady pace. This raises the ship so it can then enter the next lock, where it will eventually join Gatun Lake. The ships then pass through Gatun Lake and head toward a different but similar set of locks on the other side, where the process is repeated. This process must remain gradual, as this keeps the water flowing at a manageable rate. It takes a ship about 11 hours to make it through the Panama canal, with most of that time spent waiting for other ships to pass. Has this process piqued your curiosity? Do you want to know how the Panama Canal was built? Do you want to find out more about the science, engineering, and technology behind this great waterway? Then, do not miss our video

Construction, engineering, and architecture projects can sometimes be massive, and when they are on a whole other level we call them mega projects. So, what do mega projects consist of? Think of interstate highways, the International Space Station, the Kashagan oil fields, or the Kansai airport; these projects bring together huge resources in science and technology to build absolutely extraordinary structures. In this video, we bring you some of the world’s largest and therefore most expensive megaprojects. How much do they cost? Well, it depends on the project but we can assure you the amounts are exorbitant. For instance, The Belt and Road Initiative in China that aims to connect Asia with Africa and Europe will cost up to $8 trillion. The International Space Station costs about $150 billion to build and launch and costs up to $4 billion a year to maintain. The Kashagan Oil Fields cost $116 billion; Malaysia’s forest city is going for a whopping $100 billion while Qatar’s megacity named Lusail is reaching $45 billion. What do these mega projects have that’s so special that they cost so much? How many more mega projects are there out there? What is the most expensive one of all? We bring you all this information and more in this video not to be missed

We all know that nobody likes doing things that are time inefficient. There are some tasks that are just mind-boggling to do day in and day out, so take a look at this video montage of time-saving simple inventions to distract yourself from the dull flow of those tasks. Who knows, maybe some of these life-changing inventions will actually prove useful and you will find something that’ll actually be of help in your line of work. There are a lot of people out there with the question in their mind “How can I make this into a cool invention?” and some of these folks have the combination of expertise, time, and resources to realize these ideas and even commercialize them. One such invention is the hydraulic shears. Much like the emergency personnel staple tool, jaws of life, this one has a ‘mouth’ that helps cut down any hard material in its way. The cool invention in the video is used for cutting rebar and chains. Although let’s not get ahead of ourselves, interesting inventions don’t have to be all that fancy. Take the permeable concrete for example. It is quite hard to imagine this invention idea being used as roofing for a building, to be honest. But it’d make a nice pavement for cities’ sidewalks so that the sewage systems can have an easier time dealing with especially wet days. There are a lot of interesting inventions in the video, so don’t miss them.

Everyone holds in their pee every now and then. And that's okay! Just don't do it too often, or it could lead to some serious problems down the road. Science mania, tells you all you need to know about science: space, medicine, biotech, physiology, and more.

Today, I'm setting off on a journey toward the nearest black hole. But don't worry - I'll keep you in the know by live-streaming my entire adventure! I'll have someone to talk to during the flight, and he can help me if things get really tough! My travel buddy's name is Liam. Liam is a robot with artificial intelligence. Space distances are seriously long. That's why traveling there would take way more time than you'd like to spend on the road! For example, Voyager 1, a space probe launched in 1977, was traveling out of the Solar System at a speed of 40,000 miles per hour. If my spacecraft moved at the same speed, it would take me a whole 77,000 years to get to the nearest star! But luckily, my spaceship is much faster than that. So let the journey begin!
