INPUT ARTICLE: Article: If you want it to be Christmas-related, a snowman or pine tree might work. If it's for a birthday, try a small toy. For a personalized snow globe, try a heavily laminated photo, glued to a cork or another base.  Make sure your figure is waterproof and fits on the jar lid and inside the jar. Ensure there's a good flat surface to glue down.  Ceramic or plastic are good bets. If you're not sure, place your figurine in a bowl of water for a few hours and see if anything happens. You can also make your own figure out of sculpey clay. It's easy to find in craft stores and comes in a variety of colors. Any size can work, from a baby food jar to a spaghetti sauce jar to a large mason jar. Make sure there are no cracks and that it can be closed tightly.  Test out the seal on your jar ahead of time. Fill it with water, close it tightly and turn it over—nothing should leak out. Wash your jar with hot, soapy water, remove any labels or glue remaining, and make sure it's totally dry before proceeding. You'll also need a place your craft can dry overnight, undisturbed. Once you've got a figure and a jar, try placing it in different positions to figure out what looks best and which side you should glue down. Most craft stores or general retailers will have anything you don't already have at home. Besides a jar and a figurine, you'll also need:  Waterproof craft glue or epoxy Glitter or fake snow Bottled water, which is less likely to cloud up Glycerin or baby oil (optional, but it thickens the water and makes the “snow” fall more slowly)

SUMMARY: Pick a theme. Find a good jar. Gather your supplies.

In one sentence, describe what the following article is about: Tasting grapes is the most reliable method to tell whether or not they’re ripe. Pop a few in your mouth and chew: if the grapes are firm, sweet, and not tart, they’re most likely ready to harvest. Taste grapes from a few different clusters and different vines, so you get an idea of their overall ripeness.  Since different varieties of grapes have different natural flavors, tasting grapes is most effective if you know what the variety tastes like beforehand. If you’re not sure, visit a supermarket and taste a few grapes of the variety you’re growing at home. Ripe grapes will have a consistent color over their entire surface. Red varieties will have a deep purple color, and green grapes will look slightly yellow when ripe. Be aware, though, that grapes develop their mature color 1–3 weeks before they’re fully ripe. So, don’t judge grapes’ ripeness by color alone. Take a few grapes in your hand, and use your fingers and palm to lightly squeeze them. Ripe grapes will feel plump and full of juice. On the other hand, immature grapes will feel hard and not have any give when you squeeze them with your fingers. Table or wine grapes that are left on the vine for too long will begin to shrivel and wrinkle, and have a dried-out texture. Birds will be able to tell as soon as the grapes have ripened, and will congregate on the vines in order to eat the grapes. If you see birds gathering around your grapes, you can be reasonably sure that the grapes are ripe. Taste a few to make sure. The disadvantage of this, of course, is that the birds may eat a substantial number of grapes if given enough time. Once you notice birds gathering on your grape vines, plan to harvest in the next 2 or 3 days.
Summary: Taste the grapes to determine if they’re ripe. Inspect the color of the grapes for a consistent hue. Feel the grapes to evaluate their ripeness. Watch for birds on the grapevines.

INPUT ARTICLE: Article: . An anemometer is a tool for measuring wind speed. You can buy one online, or make a simple one yourself in about 30 minutes using the steps below. If you bought one, skip down to the step in which you count the rotations – or just read the wind speed directly, if yours has a digital display. Take four small paper cups, and punch a single hole in each one, about ½ inch (1.25 cm) below the rim. Take a fifth cup, and puncture four evenly spaced holes, about ¼ in. (6 mm) below the rim, then punch a fifth hole in the center of its base. You can use a pencil to punch these holes, if you don't have anything sharper. Stick a plastic straw into a single-hole cup, about 1 inch (2.5 cm) into it. Push the other end of the straw through two holes of the five-hole cup. Stick the free end of the straw into another single-hole cup. Turn the two single-hole cups so they are pointing in opposite directions, along the same plane as the straw. Staple the straw to the cup. Repeat with another straw, putting it through the remaining two holes of the central five-hole cup. Rotate these two new cups until each cup opening is nearer the base of the next one. In other words, the top cup points right, the right cup points down, the bottom cup points left, and the left cup points up. Staple the straws and cups together. Slide the two straws until all four cups are the same distance from the center. Stick a small pin through the intersection of the two straws. Stick the eraser end of a pencil through the hole in the base of the central cup, and push it gently onto the pin. You can now hold the anemometer by the pencil tip, and use it to measure wind speeds. Hold the anemometer upright in a windy area. Watch a single cup (draw on it with a marker if it makes it easier to follow) and count the number of times it rotates. Use a stopwatch or a friend watching the second hand of a clock to time 15 seconds, and stop you when the time is up. Multiply your count by four to get the number of revolutions per minute (rpm). For greater accuracy, count the number of rotations in 60 seconds (and don't multiply by anything). Measure the distance from one edge of the anemometer to the other to find the diameter of the rotating circle, d. The circumference of the circle, is equal to πd. This is the distance traveled in one revolution. If you don't have a calculator, you can use 3.14 as an estimate of π, or even just 3 for a rough estimate. Convert the circumference you calculated into a more useful unit for measuring wind speed (miles or kilometers). Multiply the result by the rpm you calculated to get the total distance traveled in one minute. Multiply the result by 60 to get the distance traveled in one hour (mph or km/h). Here are the full formulas in imperial and metric units:  Imperial: (__circumference__ inches/revolution) * (1/12 ft/inches) * (1/5280 miles/ft) * (__rpm__ revolutions/minute) * (60 minutes/hour) = __wind speed__ in miles per hour. Metric: (__circumference__ centimeters/revolution) * (1/100000 kilometers/centimeter) * (__rpm__ revolutions/minute) * (60 minutes/hour) = __wind speed__ in kilometers per hour.

SUMMARY:
Decide whether to make or buy an anemometer Punch holes in small paper cups. Construct one half of the basic shape. Finish the basic shape. Make a base for the anemometer. Count the number of rotations the anemometer makes. Calculate the circumference. Calculate wind speed.
