Even without a medical degree, the healthiest thing you can provide others has to be water. Forget all that chia seed and kale nonsense: you won’t survive a week without water. With this mindset, Kara Pure has got to be one of the healthiest things you can invest in. It’s a water harvester, purifier, and dehumidifier all in one. https://www.youtube.com/watch?v=Dz201BcZwa8&ab_channel=KaraWater Like any water harvester, Kara Pure takes in surrounding water vapor and condenses it into drinkable H₂O. Depending on the humidity, it can make up to 2.5 gallons (10 liters) of water a day. But before water can be dispensed through the middle of the machine, it undergoes a ton of filtration.…

My eyes light up at anything with a sleek design, so you can bet they were as wide as golf balls when I saw that square tube knife by YouTube knife maker Koss: https://www.youtube.com/watch?v=x_M-ChNcArg&ab_channel=Koss Koss used 01 high carbon alloy steel (non-shrinking steel which hardens in oil) for the blade of his project. He started shaping it by cutting out a rectangle-shaped piece and using his belt sander to cut out the knife edge. Shaping the Knife Interestingly, he used the natural shape of the metal as a guide to making the knife. One edge of the rectangle was given a blade curve, while the opposite edge became the spine. The…

While I’ve written about my fair share of dangerous products, none of them are inherently made to harm people. That changes right now, as science man and YouTuber Steve Mould covered an assassin teapot too cool to pass up. https://www.youtube.com/watch?v=jJL0XoNBaac&ab_channel=SteveMould Originating in China, the assassin’s teapot was made to poison your enemies. It does this using two hidden chambers: one housing your standard drinkable drink and another holding your enemies’ just desserts (in drink form, of course). Each chamber has a hidden hole somewhere near the teapot’s handle. To pour a specific drink out, you need to keep the hole connected to the chamber uncovered. You’ll want to keep your finger over…

The biggest problem people have with gym balls is that they take up a lot of space when not in use. The CoreFitBall Pro seeks to solve this problem by transforming the gym ball into gym equipment and a handy piece of furniture. https://www.youtube.com/watch?v=sRad4NlNPxI&ab_channel=householdproducts A Stand for a Gym Ball? It achieves this through its stand, consisting of a round top ring and a hexagonal bottom ring. Six stand lifters prop up the top ring to evenly distribute weight and prevent the ball from escaping the stand. A support structure consisting of six pillars stops any twisting and prevents unnecessary shifts in movement. The bottom ring is also fitted with silicone feet…

Everyone loves quality keyboards. They’re fast, responsive, and let you encode your thoughts into a digital format easily. A high-end keyboard can run you up to hundreds of dollars, but you can get a good, solid one for just a couple of bucks. Or… you could also try to make one, just as YouTuber Flurples has done many, many times. By far, their most popular keyboard build (one with over 10 million views on their channel) is a small 27-key keyboard taped to a piece of cardboard. https://www.youtube.com/watch?v=sVInBOLSqoM&ab_channel=flurples You read that correctly – cardboard. Thanks to the modular nature of today’s keyboards, Flurples can buy the components and make the thing themselves.…

Officially, the only way you can make your Hot Wheels cars go faster on a track is by using some variation of a Hot Wheels Track Booster – a unique track piece with two spinning wheels that rev up your cars as they pass through. https://www.youtube.com/watch?v=4xV38liv_BY&ab_channel=Dr.Engine Now, you could spend money on this official piece, but where’s the fun in that? As YouTube channel Dr. Engine shows, you can totally make an overpowered booster using LEGO Technic pieces. Dr. Engine’s first booster model consisted of two LEGO wheels mounted vertically over a piece of Hot Wheels track. It required different LEGO pieces and Hot Wheels car sizes to get the clearance between the track…
