INPUT ARTICLE: Article: You don't want coffee-flavored rice flour! Use a scrub brush or small spatula to wipe out grounds from around the blades. Never put your fingers near the blades and always unplug the grinder before cleaning it. An old paintbrush or toothbrush can also get into hard-to-reach nooks. The coffee grinder will turn the grains of rice into a smooth powder. It's best to grind the rice in small quantities so it doesn't clog or overwork the coffee grinder. If you notice the grinder getting hot, simply unplug it and let it cool down for a few minutes before continuing grinding. You may need to run the rice powder through the grinder a second time if it's still coarse after the first run. Grinders that are older or that have worn blades won't process the rice as efficiently. As you grind the rice, transfer each batch into a plastic or glass container. Once you're finished grinding, place the lid on the container securely to keep the flour fresh. Glass jars with lids or resealable bags will work instead of a container. Stick the container in the pantry or a cupboard, for example, until you're ready to use it. If you notice a rancid odor, throw it away. If you don't want to forget the flour's "expiration date," use a permanent marker or a sticker label on the container to write down the date you made the flour. You can also store the flour in the refrigerator or freezer to keep it fresh for longer.

SUMMARY: Clean out any leftover coffee grounds from the grinder if necessary. Run 2 to 3 tablespoons (30 to 44ml) of rice through the grinder at a time. Pour the powder into an airtight container, sealing it tightly. Store the flour in a cool, dry place for up to 1 year.

INPUT ARTICLE: Article: Cup anemometers are relatively easy to make and are often used as an elementary school science project. This allows children to get an opportunity to learn about measuring wind speed by making their own device. To make an anemometer, you will need plastic cups, straws, a pencil, tape, and a push pin. Position the straws in the shape of a cross and tape the middle. Then, staple the side of each cup to the end of one of the straws so they are parallel with the floor. Make sure all of the cups are facing in the same direction. Then, push a straight pin through the center of the straws and into an eraser on the end of a pencil. This will act as the axis. You should be able to blow on the cups so that they spin around in a circle. Use a coloured pencil and mark one of the cups. For example, you could put a red "x" on one of the cups. This will be the cup that is counted in order to determine how fast the cups rotate around an axis point each minute. You can either go outside and hold your device up in the wind, or you can use a fan to create airflow inside. To get a more accurate reading, make sure the airflow is not blocked by your body. Have another person count the number of times the marked cup spins around the axis in one minute. You can use a stopwatch to accurately time a minute. Record the number of times the cup spins on a piece of paper. For example, it may rotate 13 times in 1 minute. You will need to complete this step four times in order to get enough data to calculate the average number of rotations per minute. For example, the next recording might be 15 times, followed by 12 times, followed by 17 times. Add up the numbers that you have recorded and then divide that number by four. This will give you the average number of rotations per minute. For example, 13+15+12+17=57. Then divide that number by four (57/4=14.25) to get the average wind speed per minute. In this case, the speed is 14.25 rotations per minute.

SUMMARY: Make an anemometer. Mark one of the cups. Hold the device in the wind. Count the amount of spins per minute. Calculate the average wind speed.

INPUT ARTICLE: Article: In some cases, the customer service representative can stop the shipment in transit. In most cases, it will be treated as a return and shipping costs will be deducted, but you will get a full refund when the merchandise is returned. " If you haven't been able to reach the company, you can try waiting for the UPS, USPS, DHL or FedEx person and telling them that you refuse to receive the delivery.
