DIY Hinged Top Storage Benches
A hinged-top storage bench provides two useful things for any household: extra seating and hidden storage space. These kinds of benches are basic enough for most enthusiastic do-it-yourself types to manage, and can be tailored to suit almost any décor needs. Spruce up with paneling for an elega
How to Calculate a Wind Chill Factor
As temperatures fall below 91.4 degrees Fahrenheit, the human body begins to lose heat and the rate of heat loss is dependent upon the wind speed. Many formulae exist for the calculation of wind chill because there is no universally agreed-upon standard. In 2001, however, the National Weather Servic
How to Clean a Wooden Dish Drying Rack
Thoroughly cleaning wood drying racks should be done on a regular basis. Wood drying racks for plates are continually exposed to moisture which can create mold. The mold can also cause very serious illness particularly in young children and older adults. There is a need to clean these items at least
How to Make Stained Glass Panels
Stained glass panels add a prominent accent to any home, business or church. The art is an ancient therapeutic process that results in beautifully crafted windows for your home or business. You can draw out your own measured design beforehand, or else just come up with the glass design as you go alo
What Kind of Solder is Used in Making Stained Glass?
Solder is a soft metal used to bond the structure that holds stained glass pieces together. With the application of heat, solder becomes liquefied and flows into the gaps between the metal. When it cools, it solidifies and seals the gaps, holding the glass securely in place. There are several differ
How Do Compasses Work?
IntroductionA compass, in its simplest form, is a piece of magnetized material that is more or less linear in shape. It responds to Earth's magnetic field by orienting itself along a north-south axis.Magnetic FieldsA compass's function involves the Earth's magnetic field interacting with...
What Happens to Pigments at Different Wavelengths?
Light from the sun comes down in electromagnetic energy that travels in wavelengths. The human eye interprets these wavelengths in three different ways. These wavelengths interact with various materials depending on how those materials are made. And what color we see depends on how long the waveleng
How to Put More Springs in an Airsoft Gun
Airsoft guns that are spring powered rely on a single spring to propel the projectile. Adding two additional springs, each similar in diameter and half the length of the one that is in the firing mechanism, to an Airsoft gun will increase the firing range of the projectile. You must partially disass
How to Route Raised MDF Panel Doors
Medium-density fibreboard (MDF) panels can be used to create a raised panel door. By using MDF, you can cut the cost of typical door installation and get a one-piece door in a fraction of the time. Raised-panel MDF doors are cut with a pair of raised panel knives, with one cutting the inside portio
Characteristic Properties of Hydrogen Gas
The chemical element hydrogen is the most abundant chemical element in the universe, constituting approximately 75 percent of the total chemical mass of the universe. Hydrogen is also the simplest element on the periodic table, consisting of just one proton and one electron. Hydrogen gas is the gase
How Does a PIN Diode Work?
RectifierThe general purpose of a diode is to serve as a rectifier, that is, a zone at which alternating current (AC) is transferred into direct current (DC); a device that does the opposite is called an inverter. A PIN diode, however, because of the addition of an "intrinsic" layer...
Four Types of Atomic Orbitals
An atomic orbital is a mathematical function that describes the probability of an electron being in any specific area around the nucleus. There are four basic types of orbitals -- S, P, D and F -- that describe the different locations for separate electrons. Orbitals fill in a very specific order ex
What Does a Reverse Osmosis System Do?
If the concentration of dissolved substances in water is different on either side of a semi-permeable membrane, the water tends to diffuse across until the concentration is equal on both sides. This natural process is called osmosis and plays an important role in many phenomena in biology. Reverse o
What Kinds of Frogs Are in the Rain Forest?
Rain forests are ideal habitats for frogs, which need to keep their permeable skin moist. Poison dart frogs are well known in the rain forests of South and Central Americas. Most rain forest frogs are brightly colored. The poison dart frogs use their vivid coloration to ward off would-be predators,
What Are Nitrogen Rings?
There is a lot of nitrogen to be found on the planet Earth. In fact, about 78 percent of the atmosphere is nitrogen, which is atomic number 7. In the entire universe, nitrogen is the fifth most common element. It assumes a gaseous state at room temperature. Like other elements, nitrogen has the abil
How to Test Miller Diodes
Consider testing the diodes on a Miller welding device if experiencing power problems before the device stops working completely. This will save time by allowing you to locate the parts you need before the diode fails. Diodes inside Miller welding tools allow electrical current to flow in only one d
How to Make an Arrow in PowerPoint More Thick
The drawing tools in PowerPoint give you a plethora of basic shapes to draw, including arrows. The basic arrow, however, may not suit your needs. You can make fine adjustments to arrows -- or any shape -- in PowerPoint with handles that appear on the object when it is selected. Additionally, the way
Ladder Golf Building Instructions
Often played at picnics and barbecues, ladder golf is a popular outdoor activity. Played with two or more players, ladder golf sees participants compete in throwing pieces of rope with golf balls at each end onto a three-rung ladder structure to score points. Also known as bolo and hillbilly golf, l
How to Make Needlepoint Piano Bench Covers
A needlepoint piano bench cover shows off your needlepoint skills, while adding padding and a style element to a piano bench. Find the bargello style of needlepoint perfect for this project, as the design complements traditional and contemporary décors. Work bargello, also known as "flame sti
How to Stargaze With Binoculars
Stargazing with binoculars can be enjoyable for those who are interested in the stars but don't have a telescope. Binoculars provide enough magnification and light-gathering for successful viewing of such phenomena of the night sky as comets, planets, constellations and meteor showers. Binoculars ca
