Available as a 3D printable file from JBV Creative, this sine wave machine features marbles that roll in a sine wave as the machine is cranked. Hate cranking? Get creative and add a motor. Or a car engine! JBV also sells the file for a wave machine that’s only 8

This is a video that, just like the title describes, imagines various microscope objects on a human scale, beginning with a hydrogen atom resized to 5cm, and making its way through various bacteria and viruses, a city-sized sperm, and a continent sized dust mite. I learned a lot by watching

Because for every action there is an equal and opposite reaction (typically me making a sour face that indicates I’m utterly unimpressed), this is a 9-minute video of a “multiverse” reaction machine. It’s multiverse because it was made by 14 different creators in different places, with each of the 31

This is a visualization imagining you’re a beam of light departing New York City, traveling the circumference of the Earth, and returning to New York City. How long does it take? Well since the speed of light is approximately 300,000km/s and the Earth is about 40,075km in circumference, it takes

This is a video of a crab man at what I assume is a swingers resort demonstrating the incredible power of refraction, with his body seemingly completely disconnected from his head in a curved glass (read: acrylic) walled pool. Physics! Still, as wild as this is, I imagine even crazier
