Editor ThorC1138 put together this fantastic montage of movie scenes which take place in or around bathtubs. In all, there are over 150 different films, with memorable scenes from everything from Scarface, to Blazing Saddles, to The Jerk, to The Shining, to A Nightmare on Elm Street.

The Metallica track One is already a pretty grim and evocative song. Musician Poolad Torkamanrad’s stripped-down cover version only adds to the emotional weight, as he performs the tune on a Santoor, a type of hammer dulcimer originating from the Middle East. He’s also covered Dream Theater’s rock opera Lost Not Forgotten.

Old school Mazda fans will immediately recognize the Dorito-shaped rotor in the image here. For everyone else, what you’re looking at is an approximation of a Wankel rotary engine, built by LEGO machine maker Akiyuki. For a lesson on how the real engine worked, Car Throttle has a nice simple explanation.

Maker W&M walks us through the process of turning a couple of muffin tins into a miniature concrete mixer, complete with a motorized stirrer. Though in this case, its purpose is to smoothly blend instant coffee with water. It probably would make a good hot cocoa too.

Make It Extreme likes to build all kinds of crazy machines and vehicles, and their latest is pretty awesome. Imagine a motorized wheelchair that drives like a tank, and you’ll have a pretty good idea of what you’re about to see. For more detail, check out the tank tread and transmission build videos.

Independence Day is nearly upon us, so it’s time to amp up the fireworks beyond the nightly booms of cherry bombs and M80s to something a little more spectacular. Maker Peter Sripol decided to see if he and his pal Sam could build oversize versions of two kinds of spinning fireworks displays, each powered by model rocket motors.

By applying a tilt-shift photographic effect to scenes from the game, the guys from Red Dead Online Guides transformed the various environments of Red Dead Redemption 2 into miniature versions of themselves. We love how the illusion makes everything from trains to horses look so adorable. More here.

Tesla finally has some serious competition for the Model S Performance. In this episode of Jay Leno’s Garage, the star takes Porsche’s incredibly impressive electric sports car for a ride, chats with Porsche product expert Calvin Kim, and gets a small taste of what the 750 horsepower electric drivetrain in the Taycan Turbo S can do.

Over its 4-ish billion year history, the Earth has seen some dramatic changes. Algol does a great job conveying some of the milestones of our planet’s development through this animated infographic, which shows changes in the Earth’s average temperature, atmospheric composition, and day length throughout its lifetime.

We already think that Kevin McAllister’s deadly booby traps in Home Alone should have been enough to land him in juvy, but as LegalEagle points out, Kevin’s battery charges are only the tip of the law-breaking iceberg in the holiday classic.

If you follow them on any regular basis, you know that Kurzgesagt is mostly focused on videos about science, the future, and the nature of our universe. But this time, they offer up a clip that is more about improving our lives in the here and now, looking at how gratitude works, and why it’s so important for us to embrace it.

Comedian and wacky weed enthusiast Gadi Wilcherski cleverly reworked footage from America’s Got Talent with footage of himself taking bong hits, scoring big with the judges along the way. He also showed off his talents on The Voice Israel.

Shea Gunther shows how a frisbee he tossed onto the ice while skating in Cape Elizabeth, Maine kept rolling and rolling along the slippery surface on a windy day. We’re particularly impressed with his ability to keep up with it and keep it in the frame.

Amazon’s value-priced, compact Echo device plugs into any outlet, adding Alexa voice assistant capability unobtrusively to any room. It provides smart home control, weather, traffic, and other information, and has a built-in USB port for powering other devices or attaching a 3rd-party motion sensor or smart nightlight.

If you find space science fascinating, check out this clip from Kurzgesagt, in which they explain how neutron stars work. These phenomena may only be a few kilometers in diameter, but have an insanely dense atomic nucleus and powerful gravity, thanks to their origins as massive stars which have collapsed and gone supernova.

It’s a terrifying thought, but in the interest of keeping us educated about the dangers of nuclear weapons, Kurzgesagt is here to teach us just how awful it would be if humans ever were ever to detonate a nuclear weapon in a city. Even worse, we actually did this to people back in WWII.

“There are more phages on Earth than every other organism combined.” Kurzgesagt takes a few minutes to educate us on the finer points of the bacteriophage, a type of virus which is constantly killing off billions of microscopic organisms all around and inside of us.

Techmoan managed to get his hands on an a truly 1980s gadget, unopened and in its original box. The LASER FX was a home light show that attempted to replicate the experience of a concert with a laser light show. Unfortunately, its lack of an actual laser beam was its downfall. Fortunately, these days we have the LaserCube.

Add an Amazon Alexa voice assistant to your car with this tiny 3.3″ x 1.9″ gadget. It has 8 microphones to ensure Alexa can hear you over music and road noise (within reason), and lets you ask questions, stream music and audiobooks, and much more. Requires a Bluetooth or aux input, and can mount on many car air vents.

It tooks some work to modify this 1880 still camera lens to fit a Sony A7II, but the results captured in Mathieu Stern’s Weird Lens Challenge experiment produced a wonderfully ethereal and dreamy look, while still maintaining an impressive amount of detail.

Take a tour of the beautiful and serene Seashore Library, which sits along China’s Bohai Sea near Nandaihe Pleasure City. Architect Dong Gong’s design was designed to provide each occupant of its reading room with an unobscured view of the beach outside, and a sense of peace and solitude for each visitor.

For as much as we think of our planet as good old terra firma, there is so much more to be seen and explored at the beneath the surface of our oceans. Kurzgesagt takes us on a deep sea journey to learn about some of the many species that dwell in the darkest waters.

Editor ThorC1138 managed to find scenes from 100 different films in which a character spoke a different number between 1 and 100, then cut them together into a multi-movie countdown. We were really hoping for a rocket lift-off or a big explosion at the end.
