Just when we thought Kiwami Japan had run out of unusual materials to make knives from, he’s come up with another. He ironed then shaped several pairs of boxers into a sharp, functional blade. It helps that they contain synthetics. This wouldn’t work with 100% cotton.
Binging with Babish teaches us three ways to make our favorite frozen treat. The first two are easy and require only a handful of ingredients. One uses bananas as the base, while the other uses condensed milk and whipped cream. The third one is the traditional way.
I Like to Make Stuff got envious of a friend who had a large slip n’ slide, so he decided to build one out of off the shelf parts. The build’s main parts are PVC pipes, pool noodles and plastic sheets. The spray bar was made such that it can be disassembled for storage.
Lamello’s Invis Mx2 is a system of connectors and a magnetic drill drive that lets you create invisible joints without using glues, screws or clamps. The system also makes it easy to disassemble the joints. The Mx2 has a 60% higher clamping force than its predecessor.
How to Make Everything shares a brief history of fireworks, and how they work. Then he gathers the ingredients he needs to make them from scratch, including bat droppings. The resulting fireworks made for a pretty quiet Fourth of July, but technically they still worked.
Ryan & David modified the barrel of a rifle so they could load it with NERF darts, which they propelled with blank cartridges. It turns out the result is still lethal. We’d like to see this done in slow motion though, because it looks like the rifle turned into a shotgun.
Syracuse University Libraries’ Preservation department shows us how to save a water-logged book and restore it back to its original condition. All you need is some paper towels, a fan and some weights. You should also store it in the freezer if you can’t work on it right away.
After doing her best to make her own Skittles, Bon Appétit’s Claire Saffitz once again is determined to make a gourmet version of a popular food – and nobody better mess with her Lucky Charms! Of course our method for getting those marshmallows is a bit simpler.
Instructables member oliverb made an Arduino-powered digital clock that has a fun mode. It can tell the time by playing Pong with itself, updating the score to accurately reflect the time. It can also show the time in large digits or with words. Learn how to make one here.
Maker Becky Stern decided to create something none of us actually need, but is still immensely entertaining – a rolling robot made out of a baguette loaded with a wobbler circuit. It rolls along as you try to catch it, making it nearly impossible to spread butter and jam on it.
Primitive Technology’s latest relaxing video took him six months to complete. He tried growing yams before, but wild pigs and turkeys would always come and eat them. So he built a large enclosure for the potatoes. After half a year… he had harvested enough for a meal.
