Simply remember that the cut should be 5.25 inches from the bottom. To make the mark and do the most of the cutting, I utilized a tool (a cut down 2x4 with a utility knife blade). If you're doing anything else, brace the 2-liter so it can "spin" and not move up and down in respect to the knife to make an equal cut.
The goal is to create 12 equal pieces from the 2-liter bottle. These can be used for filling sandals, making flower vases, or any other project that requires clear plastic bottles. It's also important to note that larger pieces of plastic are better for creating works of art because you can see more details.
For this particular project, I chose to use some of the pieces to make a necklace. You can use all 12 pieces or just as many as you want. They work well as pendants or components of another piece of jewelry.
Here's how to make a necklace using two different sized plastic bottles:
1. Start by taking one of the smaller pieces and fold it in half lengthwise. Then fold each side toward the center, like folding a letter. Now you have four layers of material.
2. Take the remaining piece of plastic and do the same thing.
3. Using wire cutters, trim off any thick parts of the plastic.
There are several methods to split a 2-liter in half; do whatever works best for you. It made it easy to get into tight spots where a hand saw wouldn't fit.
If you don't have access to a power tools, try using an axe or a strong pair of scissors. Most large bottles can be cut into two pieces without too much trouble. The parts may not be exactly equal, but that isn't important when splitting up a 2-liter bottle.
As you can see, a 2-liter bottle is a versatile item to have around the house. You can use one as a container for storing small items, such as jewelry or coins. Or if you're feeling creative, you could turn it into a lamp, a planter, or even a toy. There are many ways to use this old bottle, so have fun exploring your options!
In order to hold the ballast in place, insert the bottom half of a two-liter bottle upside down into the top half. Secure the bottom portion inside the bottle with a little piece of tape. In the top half, place the uncut 2 liter bottle (pressure vessel). Make an effort to keep the bottles straight. Pour around 20 ml of gasoline into each bottle and seal them up as best you can. Let the rockets sit for at least 24 hours before use.
Now it's time to light them! First, find a safe place where there is no traffic and where there are no people who might be injured by the explosion. Then, take one bottle rocket at a time and follow these steps: 1 Hold the neck of the bottle tightly with your hand; 2 Keep the cap off until you're ready to light it; 3 Insert a match or lighter into the opening in the top of the bottle; 4 When the match lights, throw it over your shoulder into some dirt or grass; 5 After a few seconds, toss the bottle as far as you can into the darkness; 6 Repeat this step with the other rocket. The gas will ignite when it comes in contact with the fire, and the heat from the burning gas will burn away at the plastic, causing it to break down quickly.
Make sure you wear protective clothing and eye protection when you're playing with fire.
Round Bottle Measuring Techniques (Beer, Water, Wine)
Round Bottle Measuring Techniques (Beer, Water, Wine) Calculate the diameter. With a flat ruler, measure the bottom face of the bottle from one side to the other. This is the size of your bottle. The circumference is calculated by multiplying the diameter by pi (3.14). This is the label's width. Use a pencil and measure across the middle of the label from edge to edge.
Square/Rectangular Beer Bottles The three most common square-shaped bottles are called stubbies, pilsners, and stouts. They are measured from corner to corner with a flat tool called a measuring stick or cube.
Oval/Oblong Beer Bottles These come in two sizes: small and large. They are measured from center point to center point with a tape measure or yardstick.
Conical/Cocktail Shaped Beer Bottles Also known as tulip glasses, these are the most popular type of glass used for drinking beer. They are measured from top to bottom through its widest part.
Step-by-step instructions for measuring various types of bottles can be found below. Remember that each brand of beer may have their own definition of what shape it is so find out what they are before starting to measure.
A half-pint Similarly, a half-pint alcohol bottle isn't exactly half the size of a full pint. However, it is double the size of a quarter-pint alcohol bottle. A half pint in milliliters is 200 milliliters, or 6.8 ounces.
A half-pint doesn't exist as an actual measurement for alcohol bottles in the United States. Instead, it is referred to as a "pint and a half" or "quart." One U.S. pint is equal to 425 ml, while one European pint is 506 ml. Thus, a half-pint in Europe is 203 ml, while in America it's 6.8 oz.
The term "half-pint" came about because previous to 1960, pints and quarts were not standardized. Actually, there were two different standards for pints: one was 16 oz, while the other was 20 oz. The same applied to quarts: one was 32 oz, while the other was 40 oz. In 1960, the British Standards Institute (BSI) established one single standard for both pints and quarts. Thus, today all pints and quarts are equal in size worldwide. Prior to this standardization, manufacturers varied the amount of liquid they sold by pint or quart. For example, a manufacturer might label a product that sold well over 20 oz per pint as a "forty-ounce" bottle.
