How To: Hand color using layer masks in Photoshop CS3 and CS4

Nichole Young demonstrates how to hand color using layer masks in Photoshop CS4, which also works in Photoshop CS3. The procedure can be summarized in two stages: turning the picture you would like to edit black and white and then bringing color back into it to give it a hand-colored look. The black-and-white effect is achieved by creating a new layer over the background layer. The next step is to give the picture a warm look by adjusting the layer’s respective color balance. Then bring the c...

How To: Build war game terrain with foam

Watch this instructional model making video to begin making war game terrain out of foam. This video introduces different types of foam and the varying strengths of high density foam. It's also possible to cast plaster molds with foam. Use foam as the basic structure for war games terrains, model railroads, architectural models and miniature dioramas.

How To: Build a real lava lamp

This is how to make a near professional grade lava lamp. We did this as a chemistry project. We perfected it in a week. This took many hours to do, as we had to get the density just right. We remade it three times, also. At the very end, we combined all of the wax into a huge flask. And then it blew up.

How To: Use the levels and histogram in Photoshop

Deke McClelland explains what the Levels and Histogram commands can do in Photoshop in this video tutorial. Levels allows you to adjust the luminance levels allowing you to adjust the contrast and colors within each color channel of an image. Thus, Levels allows you to adjust the individual colors that can be found within a gradient. This command is very similar to the curves command but to a less powerful extent. It is also more efficient than the curves command. The Histogram is another col...

How To: Make blobs in a bottle with a Lava Lamp effect

The World's Easiest Lava Lamp! This is an easy, fun science activity that is great for any age. In fact, our video crew ended up taking the extra bottles home to show their friends. It is also a great demonstration of liquid density, the release of gases in a chemical reaction, acids and bases, intermolecular polarity, and well, just plain science coolness.

How To: Make a Stack of Different Colored Liquids

Here's a simple home science experiment to demonstrate to kids the different weight and viscosity of various liquids. The liquids near the bottom are more dense while the liquids on top are less dense. This can also be used to determine the relative density of solid objects. Place them in the container and see where they float.

How To: Save Battery Life on Android by Turning Off Pixels (No Root Required)

Many modern Android devices use a display technology called AMOLED. These screens differ from traditional LCD displays in that each pixel emits its own light, so a backlight is not required. Even better, when rendering a black element on the screen, AMOLED displays simply don't light up the associated pixels, meaning virtually no power is used. Since black pixels use little to no power on an AMOLED screen, more black pixels means lower battery consumption.

How To: The Best Phones for Watching Movies & TV Shows — Under $500

You might think you need to buy a thousand dollar phone to get a great experience while streaming movies and TV shows from services like Netflix, Hulu, and YouTube, but that's just not true anymore. While phone prices keep rising and the midrange segment now ranges from $300–$500, there are still cost-effective options that come with top-notch displays and media features.

How To: The 5 Best Phones for Streaming Videos from Netflix, Hulu, YouTube & Amazon Prime

For many, phones are starting to replace televisions as the primary device for watching videos. Thanks to their portability and easy to use apps, it's often simpler to watch Netflix, Hulu, YouTube, or Prime Instant Video on the smaller screen. But not every phone is suited to fit this need, so we did some testing to find the best of the best when it comes to streaming videos.
