How to Make an Olive Oil Lamp

How to Make an Olive Oil Lamp

Olive oil is a very useful product in the kitchen, but you can also use it as a fuel source. In ancient times, certain grades and varieties of olive oil were used to light up rooms and houses. If you want to go green and use an alternative fuel as a light source, here’s how you can make an olive oil lamp. (Want to know other uses for olive oil, read 13 practical uses for olive oil)

Why Use Olive Oil?

For thousands of years, people have used olive oil as a way to flavor food, but also as a source of light and heat. Among Jews, Eastern Orthodox Christians, and Muslims, olive oil is considered sacred. It is used in many religious rituals and ceremonies as a fuel for lights, lamps, and lanterns. Olive oil has a very high flash point (190 degrees Celsius for virgin oil, and 210 degrees Celsius for refined oil), which means it does not burn as easily as other vegetable-based oils. Olive oil is also odorless when burned, although you can add other aromatics like herbs to give the burning oil a pleasant scent.

While olive oil used for cooking may be used for lamps, certain grades of oil may be used for lighting purposes:
Lampanate oils are a grade of olive oil used exclusively for burning. Lampanate oils are not fit for cooking or human consumption.
Aged oils. Old batches of olive oil can be used for some recipes in the kitchen, but they’re a cheaper source of fuel for oil lamps than extra virgin olive oil. Aged oils also have a higher smoke point.
Rancid oils. Instead of throwing away rancid batches of olive oil, you can still use it as a fuel for olive oil lamps. The fuel itself may smell bad, but the burning oil will not release any unpleasant smell.
Things You’ll Need

To make an olive oil lamp, you need the following tools and materials:
Glass jar
Craft wire (the length must be at least twice the height of the jar)
Wick (you can buy wicks from an arts-and-crafts supply store, or you can make an improvised wick from scraps and strips of long-weave cotton cloth)
Long-nosed pliers
Olive oil
Steps

To make an olive oil lamp, follow these steps:
To make the wick holder, make a J-shape from the craft wire. Shape the wire so that you have a flat base for the wire to rest, a small hook at the end to hold the wick, and a larger hook at the other end to prop and secure it to the rim of the jar. The hook for the wick should be at least an inch high from the bottom of the jar.
Thread one end of a wick or other wicking material into the coil. At least a quarter inch of the wick must be above the surface of the oil when you fill the jar. That way, you don’t risk burning the oil or smothering the flame.
Fill the jar with olive oil, making sure that you leave enough room for the exposed quarter inch of the wick.
Allow the wick to absorb as much of the oil as it can before lighting it.

If you want a scented olive oil lamp, try adding some aromatic flowers and herbs to the oil. Remember that once you have used a batch of olive oil for lighting or fuel, you shouldn’t use the same batch for cooking or flavoring your food.

How to Make a Pop Up Book

How to Make a Pop Up Book

Any child is familiar with pop up books, and most even find these enticing than regular storybooks. For them, pop up books make them feel as if the characters in the story are “alive”. They also appear more enjoyable to read. If you want to know how to make a lovely little pop up book for your child, then here’s a guide to help you out.
Materials:
8.5″ x 11″ standard or construction paper
9″ x 12″ construction paper
Glue
Scissors
Coloring materials (colored markers, crayons, pastel color or paint)
Paintbrushes
Old magazines (More tips on how to get rid of old magazines)

Procedure:

Determine what story you’re going to use for your pop-up book Is it your own concept or is it an adaptation of an existing fairytale (such as Snow white, Hansel and Gretel, Cinderella)? This will let you know how much pop up characters you’ll have to make and how many pages the book will be. Write a short summary of the story as well. (For ideas see Top Ten famous children’s bedtime stories)
Make the book cover using a 9″ x 12″ construction paper. Fold it in half, then use the coloring materials to draw directly on it. You can also cut out pictures from a magazine then paste them on the front and back cover. If you want, turn to the back cover’s inside flap and write a short “about the author” section. Draw or paste a photo of the child.
On an 8.5″ x 11″ paper, draw the background for your book. You can use coloring materials and art items, such as glitter, to decorate it. Add the text if you want.
Make the tabs on the background page. Go to the undecorated side, and measure up to the 3 1/2″ to 4 1/2″ mark. From the fold, make a one inch line at each mark, using a pencil. Cut each line with scissors.


Open the folded paper, then press the created tab gently, so the fold is nor on the inside. Afterwards, close the paper. When you open it, there’s now a tab in the page’s center that pops up.
On another paper, make shapes, pictures or illustrations of the characters or story components you want to pop up. Cut them out, then fix to the tab using glue. Let the glue dry.
Glue the pop up page in the cover, but leave the back cover unglued if you have an author page.
If you want to have more book chapters, create more single pages, then attach them together one by one in proper sequence. The first page’s front half must be glued to the inside main cover, while the second page’s front half to the second half of the first page, and so on.

Pop up books are definitely a wonderful gift for an child. Turn ordinary art materials into a wonderful masterpiece with these easy steps. Everyone will surely enjoy the lovely books you make.

How to Build a Mouse Trap Car


How to Build a Mouse Trap Car

Introduction

Toy cars can be a lot of fun to build, but most of them involve the use of some hard-to-come-by materials and tools that can be difficult to use. Not so for a mouse trap car though, as you can make one in as little time as a couple of hours. They are perfect for racers, as they are self-powered. Moreover, most mouse trap cars only cost a few dollars to build (as long as you have the necessary tools around your garage). So, if you want to build your own toy car, but have no idea where to begin, the mouse trap car may be perfect for you.

The Power behind the Design

mouse trap carMouse trap cars are so much fun because they come with their own power supply built right in – the mouse trap itself. Specifically the spring on the trap. By using a string to harness the power of the spring, you can easily drive the wheels of your mouse trap car. Almost all mouse trap cars use the same principal to operate, but the car described below was chosen for this guide because it is very easy to build. After making this car, you can try out your own designs using the same propulsion mechanisms outlined here. You can create almost any design you can imagine with a simple mouse trap and a few wheels.

Materials

You need the following materials to build your mouse trap car:
  • mouse trap (of course).
  • Two metal rods that are each 4 mm in diameter and 15 mm longer in length than the width of the mouse trap you are using for the car. These rods will act as the axles for the car.
  • Four eyehole screws that are barely large enough to put the metal rods through.
  • Plywood or any other type of thinly cut wood for the wheels.
  • Two rubber bands.
  • String.
  • Washers with an inner diameter of 4 mm.

Tools

While the materials for a mouse trap car are easy to come by, you may not have all of the a tools necessary. To build the car, you will need the following tools:
  • Drill with a 3.7 mm drill bit.
  • Jigsaw (a coping saw will also work).
  • Compass to make a template for the wheels.
  • Hammer.
  • Vice.
  • Hacksaw.
  • Wood file.
  • Wood glue or super glue.
  • Epoxy (the type of glue that comes in two parts which you mix together).
  • Plies.
  • A small Jeweler’s File.

Building The Body

To begin construction, you need to use your pliers to pull the wire that holds the mouse trap open out of the trap. Also remove the bait holder, as this part is not necessary. Keep the wire catch to the side though, you will use it later. Also pull out any staples that may have held the previously removed parts in place. When everything is removed, take the eye hooks and screw them into one end of the mouse trap approximately 8 mm from each edge. If the wood begins to split as you screw the eye screw in, simply drill a small hole first.

Wheel and Axle Assembly

You can make the wheels by using the compass to create four 75 mm circles on the plywood. The wheels can be larger or smaller if you choose, but 75 mm is a good size for relatively long distance runs. When the wheels have been sketched, cut along your freshly drawn line with a jigsaw and file them down along the edges so that they are nice and smooth. Then take the rods and place them in a vice. Cut them to exactly equal length and file the ends so that they are nice and smooth as well. Cut about half way through one of the rods with the hacksaw and use the jeweler’s file to widen the slot enough to allow the wire catch that was removed from the trap in an earlier step to fit into the groove snugly. Cut a 7 mm piece of the wire catch and file down the ends. Using the epoxy, glue the piece of wire into the slot on the axle so that the wire overhangs only on one side. Let the epoxy dry overnight.

Mounting the Wheels

When the glue is dry, place the axle with the wire at the rear of the mouse trap (where the jaws of the trap rest when the trap is set). Place the other axle through its respective eye holes screws. Add washers to the end of the axles so that the axles will not slide out. Drill a hole into the center of each of the wheels with your 3.7 mm drill bit and then slide the wheels onto each of the rods.

Mounting the Engine

Now for the actual power behind the mouse trap car. Take your string and tie it to the middle of the jaws of the mouse trap (the part which snaps down on the mouse). Tie a loop in the other end so that the loop is located exactly at the rear axle. Cut off any loose ends. Take the two rubber bands and place one around each of the rear wheels for extra traction. You can glue the rubber bands into place so they will not slide off.

Powering up the Car

To use the mouse trap car, simply raise the jaws of the trap slightly and take the looped end of the string and place in over the wire that was attached to the rear axle. Reverse the car to allow the string to wind around the axle and pull open the jaws of the trap. Release the car on the ground and it will speed away.
A mouse or two at home can be easily caught with a well-crafted mouse trap, but if you’ve swarms of them running around your feet, maybe you should try these techniques how to get rid of mice. Of course, you also want to get rid of those nasty gnats buzzing around your face, so check out these tricks on getting rid of gnats, to drive them away from your home as well.

How To Make School Projects

How To Make School Projects

Have you ever been to those science fairs where science whizzes get to showcase their talents? In these exhibits, they get to show what they have learned from their classes and science textbooks. These projects can come in the form of model rockets, dioramas or makeshift volcanoes.

Anyone can actually cheat his way into bagging the best project award since manufactured school projects are sold in hobby shops. Then again, a true blue whiz kid would rather use his skills and creativity to have an edge in any competition.

Due to the wide scope of science and art, there are many different projects that you will encounter as a student. Some will require a lot of experiments with various chemicals, while others are as simple as gluing together folded paper. Here are some of the most popular school projects that until now have continued to amaze a lot of professors and students alike.

Model Rocket

A model rocket is made of cardboard, paper and a miniature engine. The engine is set to propel the rocket upward as it hurtles to the farthest ends of the school halls. It is easy to create as all you need to do is to form the various sections of your rocket by folding cardboard and paper then gluing them together. Affix the engine and the parachute inside the rocket, then you’re all set. Just make sure that you reinforce the connections of each rocket component with masking tape so that your rocket will hold together when launched.

Paper Mache Volcano

The paper mache exterior of your volcano is a product of art, while the eruption is obviously a science experiment. You can construct this project by piling up newspaper strips, until you are able to create the rough exterior of your volcano. Inside the volcano, you will create a mixture of baking soda, vinegar and red food coloring to produce makeshift lava. Remember to complete the lava mixture only when the professor asks you to present your project since the eruption will happen in an instant, once the mixture is complete.

Diorama

Among the projects tackled earlier, the diorama requires the greatest amount of creativity. You need to transform a simple shoe box and a pile of makeshift materials into a miniature version of a particular scene. The good part is, you can use absolutely anything as long as the items that you will use fit the shoe box. Use toy soldiers or small action figures to represent human activity. You can use your knowledge on paper mache to create environments like mountains and ridges. You can never run out of options when it comes to your miniature shoe box world.

Solar System

The makeshift solar system is the easiest project to conceptualize but the hardest to implement. This project will require a lot of hardwork since you have to make the planets stay upright and within their respective orbits. A nifty trick is to pierce each styrofoam planet with a barbecue stick below and a metal wire-based orbit on the side. Plant the barbecue sticks on a solid styrofoam base then affix those wooden rods to the metal wires so that the planets will stay upright.

Other Projects

There are other school projects where teachers ask their students to create random items such as lunch boxes, silly goo and rubber band guns. These items are very easy to create.
For lunch boxes, you will just need to sew together fabric and zippers until you form the lunch box. A sewing thread, needle, fabric and a few zippers are the only things you will need to create your lunch box.
For the rubber band gun, you will need to shape two wooden pegs then put them together. Add a clothespin and a box of rubber bands to the mix, then you can fire away at your classmates.
Silly goo is probably among the simplest projects that you can make. You just have to mix starch, glue and water then wait for the three ingredients to settle. You can even repeat the entire process without wasting the ingredients if you made a mistake when mixing the ingredients.

School projects are fun ways to see how you can apply what you have learned in class. Call yourself an academic genius or the ultimate whiz kid, but your claims will only hold true once you have created an exceptional school project. Let’s face it, books and lectures are merely words.
