A couple of months ago we showed you Foldify, an iOS app that allows you to create your own custom, foldable, 3D papercraft files. Your designs could then be sent to your printer, cut out, and assembled.
As you have no doubt observed, brothers and sisters do not mate. While they may find one another attractive, they find the notion of sex with one another repulsive. This is because a child produced by siblings has a high probability of sharing the same recessive genes, and recessive genes are often harmful unless coupled with dominant genes.
The video featured in this article demonstrates the function and design of a powerful form of air cannon that operates using a purpose made valve that opens very rapidly. This allows for a massive amount of pressurized air to be released at once to throw a projectile many hundreds of yards. The design of the cannon also allows the barrel and the air chamber to occupy the same space, and so it is very compact and manageable which makes for an enjoyable shooting experience.
Being lost sucks. There really is nothing worse than going to a huge event with a bunch of friends or family and then getting separated. Instead of partying with the bros, you get stuck next to this lame couple who keeps seriously making out every ten seconds. SMH.

Summer is over and autumn is here. Serotonin levels are dropping and people don't have the motivation to be outside as much anymore. So we play Minecraft instead. But walking is cumbersome, so we want minecarts. Remembering to carry one in your inventory or placing one on the tracks might be a bit much to ask for, and don't even get me started on bothering to press a button to make it go.
Playing advanced games on your phone can be pretty frustrating sometimes. Touchscreen devices are great for everyday apps and games designed solely for them, but when it comes to games that require multiple actions in conjunction with directional movement, it gets ugly.

Pumpkins are one of the cornerstones of Halloween celebrations, dating all the way back to the early 19th century. Carved jack-o'-lanterns are a great way to add some spookiness around the house, but that takes time, skill, and effort. Creating cool glow-in-the-dark pumpkins requires no carving at all—and looks...

You can buy special utensils to do just about anything these days, and separating eggs is no exception. If you don't have (or want to buy) a fancy tool to do it, the classic method is simple—just crack the egg and transfer the yolk back and forth between the two halves. But even though egg separators are pretty cheap and using the shell (or just your fingers) isn't hard to do, neither is as fun as this trick by YouTuber jifenzhongDIY.
