How to Make a Backless Bench Using Skis
Avid skiers can go through several sets of skis in a lifetime. As your skills and ski styles change, you may find yourself saying good-bye to a favorite pair of skis in favor of a new model. But your old skis don't have to be destined for the trash. You can give them new life by using them to constr
Comparing Wood Species
Trees produce wood, and it's pretty easy to identify a type of tree by noticing the shape of the tree at the bark and at the leaves. Pick up a field guide to trees if you're uncertain. Wood is another story--by the time it winds up in the lumber yard or your kitchen, it has lost its bark and leaves,
How to Display Baseball Trading Cards
A baseball card collection is often the result of years of hard work, and some of the items can be worth quite a bit. Keeping the cards in good shape is important in maintaining their value, but at the same time, who wants to shut them away where no one can see them? You may even wish to display the
Slide Rule Directions
The creation of slide rules was made possible by Scottish mathematicians John Napier's invention of logarithms in 1614. By using the logarithms of numbers, multiplication and division simplify to addition and subtraction, allowing for much quicker calculations of large difficult numbers. It was not
How to Change Network Address Translation on a PS3
Having a good network connection is the key to enjoying your online experience with a PlayStation 3 (PS3) gaming console. To get the most from your network connection, your network address translation (NAT) type should be at type 1 or type 2. Both types allow your console to be visible to others on
How to Load a Single Round in a Glock
The simplest way to load a single round into a Glock seems to involve pulling back the slide of the pistol, placing the bullet into the now-open chamber, and letting the slide slam back into place. Unfortunately, chambering a round in this manner could cause damage to your Glock, specifically the ex
How to Get Food From a Fireweed Plant
Turn your fireweed plants in to jelly, honey or add some leaves and young shoots to your mixed salad or soup.Fireweed is a good source of vitamin C and pro-vitamin A when eaten raw.

Quick Facts About Rabbits
Rabbits might be very cute and cuddly to most people, but they have many unusual behaviors that are relatively unknown to the public. From large organizations dedicated to rabbit breeders to having very healthy meat, the unusual facts surrounding rabbits are vast. They serve to remind people that ev
High School Science Experiments with Anemones
Sea anemones are beautiful, often brightly-colored sea creatures. Anemones are closely related to coral and jellyfish. Stinging polyps, anemones spend most of their lives attached to coral reefs and rocks waiting for fish to pass by close enough to them to sting the fish, ensnare them in their poiso
How to Measure the RF Output of an Antenna
While your CB (Citizen Band) or scanner radio may be generating enough power to pickup nearby frequencies, a leaky coaxial cable or a poorly aligned antenna could still decrease the quality of your radio's broadcast and reception power. But with the help of an SWR/Power meter (SWR stands for standin
What Types of Animals Live in the Congo Rainforest?
The central region of Africa is home to the Congolese rainforest. This rainforest is the second-largest in the world, according to Greenpeace, with the Amazon rainforest taking the top spot. Much of the rainforest is within the Democratic Republic of Congo, although other rainforest areas...
Commercial Uses of Methane Gas
Methane was first isolated in the 1770s by Alessandro Volta while he was studying marsh gas at Lake Maggiore on the Swiss-Italian border. It is extremely flammable and relatively abundant, which makes it an attractive fuel source. Burning methane does produce carbon dioxide, but not as much as carbo
How to Operate a Dummy Load
A dummy load mimics the electrical resistance of an antenna in a radio transmitter system. Operating a transmitter without an antenna or dummy load can cause damage to the transmitter. Resistance of the dummy load is measured in Ohms. Use a dummy load with a rated resistance higher than required for
How Does a Power Plant Steam Generator Work?
Electricity is a necessity in modern society, and although alternative power sources, like solar or wind power, are increasing in popularity, much electricity comes from steam power plants. Steam power plants make use of generators to create their electricity.
The Life Cycle of a Medium Mass Star
Medium-mass stars like our sun have estimated lives of more than 10 billion years. They begin by condensing out of gas and dust, have a long middle age, swell up for a while, then contract and slowly die out.
Automatic Voltage Regulator Functions
An automatic voltage regulator, AVR for short, is a device that is designed to automatically control, adjust or maintain a constant voltage level. Automatic voltage regulators come in a variety of sizes and designs. Only a certified electrician should handle this device as it involves a...
Do Different Types of Aluminum Cans Melt at Different Rates?
The melting point of a solid compound depends on its molecular structure, and aluminum cans are no exception to this rule. Bob Dick and Andy Trageser at the Pittsburgh Supercomputing Center say that over time the weight of aluminum cans has been decreased by alloying aluminum with various materials
