Have you ever wondered how your clothes get their color? Dyeing textiles is a very complicated process and involves a lot of chemistry. Not only are the properties of the dye and fabric important, but the dyeing conditions also have to be exactly right to get optimal color adsorption. Curious about how it works? In this science project, you will color wool with Kool-Aid® and explore the chemistry of dyeing.

How does the intensity of a light source change as you move away from it? This project describes a method to verify the inverse square law: how light, sound, electrical signals, and gravity each decrease with distance from their source. It does not matter if you are talking about a lightbulb or the sun; this law still applies!

Virtual reality headsets can make you see something that isn't really there, but can you feel an object that isn't there? In this project, you will build a device that lets you feel invisible sound waves in midair.

This project is a follow-up to the Science Buddies project Explore Optical Illusions: Build an Infinity Mirror, which shows you how to build a basic infinity mirror using light emitting diodes (LEDs) and arts and crafts materials. What if you wanted to build an infinity mirror that could change colors, like the one in Figure 1?
Figure 1. A color-changing infinity mirror.
You can do this by using special RGB (red, green, and blue) LEDs. Just like the pixels…

Plenty of animals, like dogs and horses, can walk and run on four legs, but what about robots? Sometimes legs are better than wheels—try out this project to design and build your own quadruped walking robot!

Could you use a magnetic slime "robot" to retrieve a battery accidentally swallowed by a small child? Scientists think so! Watch this video to learn about magnetic slime that, when driven by external magnetic fields, can squeeze through small spaces and even grasp objects.
Can you make your own magnetic slime robot that can accomplish some of the same tasks demonstrated by the researchers? You can start by adding iron filings to slime to make your own magnetic slime (see this Science Buddies…

Have you ever been annoyed by poor Wi-Fi reception for your phone, tablet, or laptop? Do you wish there was something you could do about it? In this project you will learn how to build a parabolic reflector that you can attach to the antenna of a regular wireless router to help boost its signal.

When you think of robots, you might think of things made out of plastic or metal...but what about living materials? Living materials have one big advantage: they can heal and repair themselves if they get damaged. Since it might not always be easy to repair a damaged robot (for example, a robot on another planet), some scientists want to figure out how to include living, or biological, materials in them to create "biohybrid" robots. In this project, you will create your own simple biohybrid…

Have you ever wondered how virtual reality works? With virtual reality, people feel like they are in one place while knowing they are somewhere else. In this project, you will show the same phenomenon on a smaller scale. You will use the McGurk effect to show how you can hear one sound, while knowing a different sound is physically there. First, you will produce such an experience using audio and video, and then measure the strength of the phenomenon.

We encounter an amazing array of colors every day, from the greens of plants and the many colors of their flowers, to the pinkish blue of a sunset, to the artificial coloring in beverages. How do we perceive all of these colors? When light hits an object, some of that light is absorbed by the object, and the light that is not absorbed is what we see. In this science project, you will build a simple spectrophotometer from a cell phone and use it to investigate how visible light is absorbed by…
