When I was four, I had that stupid idea of stopping the blades of an electric fan… using my tiny fingers. Really just a child curious about things. Long story short, I wasn’t able to point at things for a while. But, the good news is I still have that finger (in case you were wondering), satisfied my curiosity, and learned a very important lesson. That was with a fast-spinning fan. But what would happen if you stuck your finger in something slower? Like say, a car window? https://www.youtube.com/watch?v=GtoDsJDYWX4&ab_channel=WilliamOsman After finding out a German-made Volkswagen’s windows would automatically pull back once it has detected an obstruction, YouTuber William Osman turned into…

Have you ever wondered how one of those perpetual Heron’s fountains works? You know, those ones with a seemingly infinite supply of water? You could look it up on Google, but where’s the fun in that? Instead, why not have YouTuber DaveHax explain it with a miniature Heron’s fountain built out of bottles and straws? https://www.youtube.com/watch?v=K49QOM_B8dA&ab_channel=DaveHax The build itself is quite simple. Drill a couple of holes slightly larger in diameter than the straws into three bottle caps. Two of these caps should be glued together, allowing one bottle to stand upside down atop the other. The upside-down bottle should have two drilled holes on its bottom (which is now…

The right professional camera isn’t just about the unit that boasts huge sensors and high-resolution capabilities. It depends on the needs of the users, so there is really no perfect camera for all. So, while most individuals are looking for high-res cameras perfect for casual portraits and still life, some might need cameras with a fast and reliable AF system for capturing moving subjects. Canon EOS R5 is probably, by far, the unit that can only tick most of the boxes on your list. Besides the 45 MP full-frame CMOS which should be more than what you’ll need to shoot quality images. Yet, its Dual Pixel CMOS AF II is…

Mark Rober, a former NASA and Apple engineer, always has something up his sleeve. This time, his newest project is a domino-stacking robot he nicknamed “Dom” (short for “Dominator”). https://www.youtube.com/watch?v=8HEfIJlcFbs&t=130s&ab_channel=MarkRober As said, Dom has one specific function: to stack as many dominoes as fast and as accurately as possible without a single misplaced piece. Why, you ask? Because stacking millions of dominoes in lines would probably cost any person’s sanity. Plus, who doesn’t love toppling them over without the fear of doing it again because you have a reliable domino-stacking robot? This makes the robot extra special compared to Mark’s previous projects. And though it took him and three undergraduate…

Even with the human body’s natural ability to adapt, we aren’t exactly made to withstand too much g-force. You can chalk this up to humans’ inability to fly or run at supersonic speeds. So, why do some folks even bother going to high-G training? Well, it’s to up their g-tolerance before getting in an aircraft. But how do they do it? And how did it start? In the 1950s, pilots would willingly strap themselves to rocket-propelled sleds and would get boosted across vast open areas. After attaining the specific amount of g, the sled would slow down with help from water troughs. Needless to say, it wasn’t the safest method…

Sports or action cameras have a specific set of purposes that gives them a specific place and category in the photography world. Though most phone cameras now can exceed the photo and video quality of action cams, the latter offers much more convenience in specific situations. Due to their sizes, they can be easily attached
