That's about 3.8 centimeter (1.5 in). 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 ½" (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?

If you're standing around a group of your friends and you're towering over them, then yeah, you're tall. Check out a photo of you and your friends and see where you stack up -- if you're a head above the rest of your friends, then yep, you're probably tall. But remember that it also depends on who you hang out with -- you won't look so tall if you're hanging out with members of the volleyball team instead of regular girls. If you regularly have a hard time finding pants that fit you because they are always too short, then yeah, you're tall. You may even hear your girlfriends complaining about always having to hem their pants because they are too long and may wonder what the heck they are talking about. You may also have a hard time finding shirts that don't look like belly shirts when you put them on. As for shorts, if you're tall, then it may be hard for you to find shorts that cover much of your legs; if your school has a dress code where your fingertips have to reach the bottom of your shorts, it may be nearly impossible for you to find a pair of shorts that is long enough. If everyone around you asks if you play these "tall girl" sports, then it may be a sign that you are taller than average. This can be annoying if you don't actually play those sports -- or any sports at all! People love to assume things about others because of their looks, and you shouldn't get too discouraged by this. Though this measurement can change depending on what country you're from, in general, if you're taller than this, you can be considered tall. In general, girls hit puberty between the ages of 8-13, and boys hit puberty between the ages of 9-15. This means that, if you feel tall but you're only 11, you may just be developing faster than a lot of your girl friends, and may be taller than the boys around you, who will take a bit longer to catch up. If you're still in the midst of puberty and many of your friends haven't hit puberty yet, then don't worry -- in a year or two, you'll be surprised by how quickly you stop feeling like "the tall girl." If you're in a room full of people, and your friends can spot you right away from across the crowded space, then yeah, it may be because you're so tall that you stand out easily. There's nothing wrong with that -- who says that standing out is a bad thing? Whether you're sitting on a plane or in the passenger seat of your friend's car, if you always feel like you have to move your legs to one side, recline the seat, or just contort your body to get your feet on the ground, then you may be a tall girl. If those middle school or high school dances are awkward because any guy you dance with is just short enough to be eye-level with your chest when it's time to sway to a slow song, then yeah, you're a tall girl. But don't be discouraged -- there's a good chance that a lot of the guys you know haven't stopped growing yet. You can't help being tall. But still, you find yourself feeling guilty whenever you go to a concert or the movies, because you just know that the person behind you can't see a thing. There's not much you can do about it -- except slouch in your seat. If this sounds like you, then you're probably a tall girl.
