Whenever you have made a really great thing, the idea of duplicating it comes automatically to mind. But the first one of anything takes a lot of time to make and you probably don’t want to make that effort for every following copy. So it makes sense to make a mould of it to make the copying easier. But if the shape of the object doesn’t allow for a one part mould, you need to make the mould in different parts. In this video from Tested, Frank Ippolito shows us just how easy it is to make a two-part silicone mould when you know how to do it. Do you want to know how to do it? Then just watch this brilliant video!
Most electrical motors uses electromagnetism in order to transform electricity into mechanical work, but there’s another type of motor, the electrostatic motor, that works differently. Instead of using magnetism, electrostatic motors uses high voltage to attract and repel parts of the motor, causing them to turn. There are many ways of making such motors, but most tend to have very low strength and torque. There are the exception to this rule though, and in these videos from RimstarOrg one such exception is studied in detail. It is called the “Corona motor” and apart from being cheap to build, it also have high enough strength and torque to be a viable motor for practical applications! The downside is that it needs very high voltages, and if you try this build, be extremely careful not to get a shock! And if all possible, avoid using high voltage transformers that plug into the wall socket. They can kill. We are not kidding.
Do you think foam sheets can’t be used for Hollywood grade suits? Then check out the video below! Foam materials are vastly underrated and have enormous potential, especially when it comes to props, costumes and movie-making! In this video, we hope you will be convinced that foam materials doesn’t only look great, it is also a very cheap and easy way of making beautiful costumes! Many thanks to Indy Mogul, not only for making this technique accessible for everyone, but also for their astonishing work on making a Hollywood grade 12 minute Sci-Fi short film on a backyard budget! Indy Mogul rocks!
Who doesn’t like candy, i ask you who?! Of-course, they are full of sugar and other unhealthy things, but now there is a solution: Fake candy! Sure, it doesn’t taste as good, and could suffocate you if you try to eat it, but man, do they look great! In this excellent instructional video from simplekidscrafts you can learn how to make fake ornamental candy from ordinary objects like beads, colorful paper, tape, yarn, toothpicks and much more. This particular video shows how to make miniature candy for dolls, but you could easily scale it up. How about making a wrapped candy out of a bowling ball?!
