Make your own snow crystals!

Snowflakes may not be a functional thing, but they are definitely beautiful. But instead of trying to catch them out in the wild, why not grow them yourself? In this video from SciFri, Ken Libbrecht, Caltech physicist and author of “The Secret Life of a Snowflake” tells us exactly how you can do this for only a couple of bucks! Now that’s some cool science! (Pun intended)

14 great photography tricks!

Okay, you are done. You have worked your butt off for several weeks, maybe even months, but your project is finally complete, and it is AWESOME! You wish to show it to the world and what better way than to take pictures or record a video about it? But why not add some really cool camera tricks to the view, some eye candy if you will? You can make gorgeous looking pictures/videos with very simple tools and materials. COOPH has made these extremely awesome tutorials that can help anyone to make super cool recording effects! And if the only camera you have is in a mobile phone, you can still make some great pictures, as demonstrated in their video below. So what are you waiting for? Go ahead and make some eye candy. Your viewers will enjoy your project even more!

How to paint with masking fluid

We all know about masking tape, but do you know what masking fluid is? Well Jessica Joaquin is here to show us what it is, and we have to say, this is an extraordinary handy material. Imagine masking a complex curved line on paper or on an object with masking tape. The only way to do it is to tear the tape down to itty bitty pieces and carefully puzzle them around the curves. A very slow and tedious work! But what if you could apply the masking tape with a simple painting brush? Much easier right?

Just watch this and save yourself a lot of tedious work in future projects! Also, bookmark the Lunapic site mentioned in this video, it is a great free tool to use for simple image and photo manipulations. You don’t even have to install any program!

 

How to make a static electricity motor

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.
