That's about 3.8 centimeter (1.5in). The best kind of "mirrors" for this are acrylic -- or those cheap little locker mirrors they sell everywhere when it's back-to-school season. They're not really mirrors, so they're fairly easy to cut into with a box or paper cutter. Be sure to leave a small gap between each strip. "Small gap" here means about 1/8" (.3 cm). Then, tape the mirrors together (along the gaps), bend them into a triangle shape, and set aside. 85 cm). This is easiest with a box cutter, but scissors will do. Just be careful not to stab yourself! Here's how: Place one of the circular ends of your tube flat on a piece of paper -- contact paper is best, but construction paper or even gift wrap will work, too. Cut about 1" (2.5 cm) around the traced circle; with that extra 1", cut little notches around the circle so it bends more easily (it'll sort of look like a firework). Cut a triangle or circle in the center of the paper to view through. Center the cardboard tube on top of your circle and secure the edges with tape (unless you're using contact paper, of course). Get an empty plastic container or two and trace two circles using the end of your tube (permanent marker is easiest to see). With an object that's about " (1.25 cm) larger than your tube, draw around the previous ones. Then, cut around the each of the larger circles with scissors. Lenses! With one of the circles, cut notches all the way to the inside of the smaller circle -- this'll be called lens 1. It should sort of resemble a gear. With the other circle, cut notches to the outside tracing of the smaller circle this'll be lens 2. Lay them flat against the table and bend the notches upwards. To begin, slide your triangular mirror inside the cardboard tube. Take lens 1 and place it inside your tube against the edges of the mirror, notches facing up; this should form a sort of makeshift pouch. Place your selected beads, sequins, glitter, gems, and/or confetti on top of this plastic lens. Cap your gems using lens 2, notches facing down, and use masking tape to secure it all together. The easiest way to make this kaleidoscope look as impressive as possible is contact paper -- so long as you work out the bubbles! But you can also use construction paper or even gift wrap to jazz it up. And then add on some glitter or stickers if the urge strikes! If there's some tape exposed where you secured your lens, cover it in glitter! It's easy and mess-free if you pour your glitter in the crease of a folded piece of paper. Just coat the very tip of your kaleidoscope in glue and place it in the crease, rotating it around until it's fully coated. Done! Now all you have to do is hold it up to the light and look through it. The light bounces off the mirrors, creating the kaleidoscope effect you see inside. What happens when you jostle it? When you turn it slowly? Can you ever create the same image twice?

Interest is paid on the total amount of money borrowed, also known as the principal. In the case of an investment, your principal is the total amount of money you invested. This amount is represented in the simple interest formula by a "P." For example, suppose you bought a car for $12,000. You paid a $3,000 down payment and financed the rest. The principal on your car loan would be $9,000. Interest rates are typically expressed as a percentage. Divide the percentage rate by 100 to turn it into a decimal. Use that decimal in the formula. For example, if your car loan had an annual interest rate of 7%, you would express this in the simple interest formula as 0.07. Loans are usually made for a certain number of years, represented by "t" in the simple interest equation. However, for some loans, such as car loans, the length of the time period is expressed as a number of months. For this simple interest formula, you would need to turn months into years. For example, if you took out a 60-month car loan, you would divide 60 by 12 (the number of months in a year) to determine that the loan is 5 years. The formula I=Pin{\displaystyle I=Pin} can also be used if you have a loan term expressed in months or weeks. This formula is a little different in that "i" represents the interest rate during each period and "n" refers to the number of periods. You would divide the annual interest rate by the number of periods in a year to get the right value for "i," then use the total number of months for "n." Whether you adjust the time period or the interest rate, you should get the same result. Once you have numerical values for the pieces of the formula, multiply them together to determine the amount of interest owed over the life of the loan or investment. Continuing the example, you financed a car with a $9,000 loan at 7% interest for 5 years: P=9,000{\displaystyle P=9,000} r=0.07{\displaystyle r=0.07} t=5{\displaystyle t=5} The interest owed is $3,150. 3,150=9,000x0.07x5{\displaystyle 3,150=9,000x0.07x5}. When you pay back a loan with simple interest, you pay the principal amount that you originally borrowed plus the total interest on that amount. To find the total amount, add the interest back into the principal using the formula I+P{\displaystyle I+P}. Continuing with the previous example, the total amount owed would be $12,150. 3,150+9,000=12,150{\displaystyle 3,150+9,000=12,150}. You can combine both equations together if you're looking for the total amount of money that will be accumulated over the life of the loan or investment by using the formula A=P(1+rt){\displaystyle A=P(1+rt)}.

There are many benefits to having smaller breasts, such as not needing to wear an underwire bra and having an easier time with breast exams. Physical activity is also easier for women with small chests, and you don't have to deal with back pain caused by large breasts. Another benefit is that you'll have an easier time finding clothes that fit you. For example, you won't have to worry about being unable to close a button-up blouse. Being flat-chested shouldn't define you. There are lots of other parts of yourself to appreciate, so spend some time thinking of areas of your body and mind that you do love. For example: You may have beautiful hands, long legs, or a great bum. You might be a great listener, a loyal friend, or have a great sense of humor. Remember that you are beautiful and worthy, no matter the size of your chest. Looks only make up a small part of you who are. Create a list of skills and talents you possess and activities you enjoy to remind yourself of all the reasons you have to be confident. For example: You may be a strong swimmer or be able to make every free-throw you shoot. You might be well-organized, a great friend, or very artistic. You may enjoy singing and dancing, excel in math, or have the ability to cheer up anyone who is sad.
