Blow up a balloon without using your mouth or your hands. The balloon should inflate inside the bottle. Why it happened: As the air in the bottle cooled, it contracted and took up less space in the bottle. Air from outside the bottle rushed in to fill the space and inflated the balloon. What happened: In the experiment, the clay represents the Moon, the flashlight the Sun, and the orange is the Earth....

It’s called a centered double decrease because it doesn’t really lean to the left or the right. Instead, the slipped stitches recede and the center stitch becomes prominent. To begin a S2KP, work to where the decrease needs to be and slip two stitches as if to knit, slipping them at the same time. This is the same sort of move you make to begin a knit two together. As you can see, this decrease makes the slipped stitches recede into the background while the knit stitch pops out, making a centered double decrease that’s great in lace knitting and other times you might need to take out more than one stitch at once....

Practice Sketching For rough practice sketches, pretty much any paper will do. Office printer paper is cheap and smooth and doesn’t “bleed” if you like to sketch in pen. Bulk newsprint pads are functional, if not robust, and useful for large preparatory sketches. Canson Biggie Sketch or Strathmore 200 series are good, economical choices. Expressive Sketching Expressive sketching calls for paper with a slightly rougher texture. Generic sketchbook paper has a fibrous texture that allows specks of white to show through the shading and a toothy surface that will hold onto the softest of mediums....

It’s also the day that marks the running of the Boston Marathon, the oldest and most prestigious annual marathon in the world. The race attracts more than one million spectators and 25,000 runners, a far cry from the 15 runners that took to the course for the inaugural race in 1897. Boston’s legendary course has the reputation of being both gorgeous and nasty at the same time. Its hills have swallowed even the most elite runners....

Usage on Coins The United States Mint first used E Pluribus Unum on coins in 1795, on the Half Eagle $5.00 gold piece. The reverse design motif is based on the Great Seal of the United States and depicts an eagle holding a banner in its beak bearing the motto. The motto was first used on a silver coin three years later and appeared on all U.S. gold and silver coinage shortly after that....

At new moon, the Moon is lined up between the Earth and the Sun. We see the side of the Moon that is not being lit by the Sun (in other words, we see no Moon at all, because the brightness of the Sun outshines the dim Moon!) When the Moon is exactly lined up with the Sun (as viewed from Earth), we experience an eclipse. As the Moon moves eastward away from the Sun in the sky, we see a bit more of the sunlit side of the Moon each night....

Optical Lens On the front of a camera lens there is a glass lens that focuses light into the camera body and onto the film. Inside the lens body, there are several other optical lenses that further refine the image. These lenses are sometimes called “elements”. Filter Threads In front of the first optical lens, there is a small ring with screw threads cut into it. These threads allow for filters and other accessories to be easily attached to the front of the lens....

Two Bros Bows I first discovered Two Bros Bows while working at a toy store. Our owner had just come back from Toy Fair and told us about these toy archery bows being sold by a duo of young brothers from North Carolina. Not long after, we had people coming into the store looking for them. Two Bros Bows is now a million-dollar company. So how did this phenomenon start?...

Since most modern coins are mass-produced in large quantities, it is common that the coin may have minor nicks and scrapes on its surface from the production process and be transported in bags and bins. However, these minor imperfections are not from the coin circulating in commerce, and hence the coin is still considered an uncirculated coin. Numismatists grade uncirculated coins by evaluating the quantity of these minor imperfections. Grades for uncirculated coins uses a scale that ranges from MS-60 (a lot of marks and imperfections) to MS-70 (a perfect coin with no marks)....

Why would furniture companies use a manufactured wood product simulated to look like hardwoods? The answer is simple. Manufactured wood products are far less expensive to buy than hardwoods. Furniture constructed by applying veneers over core carcass of manufactured wood can cost a fraction of what solid hardwood costs, making good furniture more affordable for a wide range of consumers. Particle Board Composition The term particle board—also known as particleboard, low-density fiberboard (LDF), or chipboard—is an engineered product containing wood chips, sawmill shavings, and sawdust, bound together into sheets with chemical resins and glues....

Mixing Secondary Colors At its most basic, color theory tells us that if we mix equal parts of two primary colors—blue, red, and yellow—we will create either green, orange, or purple. This is the foundation for the color wheel and a lesson that is often taught in elementary art classes. Blue and yellow make green.Yellow and red make orange.Red and blue make purple. The secondary color you actually get will depend on the proportion in which you mix the two primaries....

Quilting doesn’t require applique, but appliqued quilts can be quite beautiful. You’ll see applique used on all sorts of clothing, too. Kate Middleton’s wedding dress and veil are examples of appliqued lace. Applique in Quilting Applique is a term that quilters use in a few different ways when talking about their quilting projects: Applique, used as a verb, is the process of sewing (or attaching in another way) smaller pieces of fabric onto a larger background....

The best size of grog for most purposes is a 30/80 mesh. This means that the grog is small enough to go through a screen with 30 openings per inch, but is too large to go through a screen with 80 openings per inch. Commercially available grog almost always has some iron in it and may not be suitable if you want a pure white clay body. For hand building, grog in a clay body reduces the shrinkage and makes it less likely that a piece will crack during drying and firing....
