The massive offices that represent so much of the American economy are an ecological disaster. They aren't heavy manufacturing, but they use incredible amounts of paper, electricity, and other resources. This video will give you some tips for making you office more green, saving electricity and paper and making the Earth a better place.
An electrophorus is a type of capacitor that generates electrostatic energy. Most of you probably know this force as static electricity, the domain of door handles and polyester shirts. It can be used for all sorts of other fun science experiments though, and this video will show you how an old hard drive, some plastic, Styrofoam, foil, a cat, and other simple materials can be used to make a a simple functioning electrophorus.

A Peltier module allows you to turn heat into electricity. Because you can place it in areas that are normally warm anyway, the electricity created is "free" in a sense, though it does work best when one side of the module is cold and the other is hot. In other words, all you'll need for this project is the Peltier module and a cooler surface such as soil or water, and a warm area such as a well lit window or warm pan.
In the first video, you'll see how contact between different materials can result in attraction or repulsion. Experimental results are discussed that led to Ben Franklin's one fluid theory of electricity. It explains how clues were found from rubbing different materials together.
Build an old static electricity capacitor which will shock the electricity of your TV or computer screen. The full discharge of this Leyden jar can be deadly. Make it smaller if you want to try with your kids.

In this rapid fire video, Mr. G introduces us to the idea of atoms, static electricity, and opposing charges. We've all seen a balloon pick up static electricity from a wool sweater and stick to a wall, but watch how the same charged balloon can bend water! For this experiment you'll need a balloon, a wool sweater and a running tap.
Eddy Currents are little circles of electricity created when metals are moved by magnets or even when magnets are moved by metals. To understand this practically take a regular piece of cardboard and drop it in between a horse shoe magnet. It drops normally with out being effected by the magnet. This is because the cardboard does not conduct electricity. Therefore it does not cause any eddy currents. But instead if you use an aluminum piece in the same way, it falls very slowly, because alumi...
In this tutorial CreativeIceDesigns shows you how to make really cool electricity text effect by using Photoshop. To do this you need to open Photoshop and create new document. Layer will be black. Go to Type tool and type the word which you want to give effect. Now duplicate the layer and hide one. After that go to filter, stylize and wind option. Give this effect from all side. Change the color and unhide the text layer. After watching this you will be also able to make electricity text eff...
Objects become charged when rubbed against one another. This happens because negatively charged electrons flow from one object to the other.
MAKE magazine never fails to amaze. And this time, John Park tackles a DIY wind-powered generator—and he shows you how to do it! Before you start watching the video tutorial, make sure to download the PDF of this project for reference.
Static electricity might seem like magic but you don't have to be a wizard to get rid of it. There are simple steps you can take to reduce the amount of static electricity in the air or on you by using some items you probably have at home.
Hydrogen can be used to improve mileage. The hope with this method is that hydrogen will increase the amount of gasoline combusted and increase fuel efficiency, as you trickle hydrogen into the tank. Often propane is used to increase gas mileage. The studies are still being done. There's no official data at present, but there is significant experimentation.
Do you even know what a Leyden jar is? Well... it's an early form of capacitor made from a glass jar with layers of metal foil on the outside and inside. This video tutorial will show you how to make a Leyden jar to store static electricity. This Leyden jar will give you a powerful shock!
Gummi Bears are great for science experiments due to their gelatinous makeup. In this video you will learn how NOT to make a Gummi Bear conduct electricity, but in fact how to use them to demonstrate osmosis and crystallization by preparing them for conductivity.
Glass normally doesn't conduct electricity, but there are all sorts of cosmetic and industrial applications for conductive glass. There are easy and hard ways to make it. This video will show you one so easy you can do it at home with only four ingredients: glass, Stannous Chloride, toothpaste, and alcohol.
Electroluminescent devices need electricity to light up, clearly, so if you're working on an EL project building a proper power supply is crucial. In this video you'll learn how to make a DIY power supply for your EL projects that is safe, effective, and cheap.
Electroluminescent (EL) materials light up when electricity passes through them, as opposed to more common incandescent lights that respond to heat. EL displays are becoming very popular in advertising and art,but getting them or the materials to make them can be expensive. Watch this video to learn how to turn an LCD into a simple EL display, and also how superglue can be used as a cheap dielectric in this sort of project.
This video demonstrates the relationship between electricity and magnetism and shows how to construct an electromagnet using a 4 inch iron nail, 5 meters of copper wire and a 1.5 volt AA battery. Electromagnetism was discovered by the Danish scientist Oersted. Electromagnetism is the science behind electric motors, solenoids, speakers and electromagnets.
Normally, when you scroll down a webpage in Safari on your iPhone, it automatically hides the bottom toolbar and minimizes the top Smart Search field. But as soon as you scroll back up, they both reappear, which can be pretty annoying if you don't need them. Apple's iOS 13 update brings many new features to Safari, one of which solves the toolbar issue so you can keep it hidden when reading.
In this tutorial by Lowe's, we learn how to install exterior motion-sensor lights with Lowe's. First, you will need to pick out what kind of motion sensor light you want. Most of the kits you purchase will come equipped with all the things you need, you will just need to supply the hardware. You will need: a screwdriver, circuit tester, electrical tape, silicone caulk, work gloves, and safety glasses. Open up the package and find the directions inside of it. After this, turn off the electrici...
In this Education video tutorial you will learn how to build a wind turbine with PVC windmill blades. This project when completed will charge a 12V battery. You can turn a motor in to a generator. When you spin the shaft on the generator, electricity is generated. So you get a motor with a flywheel and attach the turbine blades to it. When the blades turn with wind action, electricity will be generated. Take PVC pipes, 8" in diameter and 24" long. Cut the blades out of the pipe as per directi...
This video shows the viewer how to start a fire without sing matches or electricity. This is done by first selecting a fairly large dry log. The aim is to ‘chip’ or peel smaller pieces of wood off from this log. These pieces will burn more easily and as such will make it easier to start the fire – a small hatchet is a useful tool to use when breaking down the larger log. Once you have the kindling place it on an alcohol wipe. Then use a flint or a fire steel to ignite the alcohol wipe. Once t...
Like a lemon, a potato can produce electricity. This science experiment was prepared by Ebtisam Al Anzoor and demonstrated by Mustafa Daif. The electricity is proven using an analog micro ameter. The positive is copper from a penny or copper coin while the negative is a galavanized nail. The potato releases a charge and is further proven when it is connected to a calculator. You can daisy chain the potatoes for a greater charge.
In this clip, you'll learn how to minimize app windows into the dock on an Apple computer running the Mac OS X operating system. For more information, including a complete demonstration of the process and detailed, step-by-step instructions, watch this home-computing how-to.
