Use a pair of scissors to carefully cut the top of the bottle off. Cut just beneath where the bottle begins to narrow. A plastic soda bottle works best. Be sure to remove the paper label completely. Parental supervision may be necessary for younger children when cutting the bottle. Pour in the pebbles in the bottom of the bottle. Soda bottles are never flat. Pour in the pebbles to even out the bottom and to keep the gauge from tipping over if it's windy or the downpour is extremely heavy. Remove the cap from the top of the bottle and turn it upside down. Place it upside down on the bottom part of the bottle so that the top is pointing downward. Secure the funnel in place by lining up the cut edges and taping the two halves together. Make sure that the top half is firmly held in place, and that there aren't any gaps between the two pieces of your gauge. Cut a long piece of duct tape and place it on the side of the gauge so that it creates a straight vertical line from the bottom of the bottle to the top. Take a marker and a straightedge to draw a horizontal line just above the pebbles. This is the bottom of the gauge. Use duct tape for it's strong adhesive properties. Masking tape, or other forms of tape, may come loose when soaking wet. Take a ruler and place it against the tape so that the 0 lines up with the bottom line you have marked off. Use a marker to mark off every half-centimeter or half-inch along the tape until you get to the top. Label the centimetres or inches from the top to the bottom. You want to be sure that your measurements will be easy to read throughout the duration of the experiment. Every half interval does not need to be labeled. Label every other mark by beginning with the second mark as 1 inch or cm. The marks in-between each label are a half measurement. Make sure to wait until your marker dries on the tape before placing your gauge in the rain. Do not use washable markers or apply markings while in the rain. If you have to reapply new tape or new markings midway through the experiment, your results may be considered inaccurate. You may use any unit of measurement your experiment calls for. You can mark off every quarter-inch, eighth-inch, or centimeter. Set your gauge on a level surface. Make sure it isn't obstructed by any branches or in the way of people walking by. Pour some water in the bottom until it reaches the 0 mark and then you're ready to collect. You may also use coloured jelly instead of water to give yourself a reference point of where to start measuring. Use jelly or oil rather than another liquid as those may dissolve and mix into the water, ruining your measurements. These bottles are not evenly shaped on the bottom so you must account for this by establishing your starting point. Make sure that the gauge is in a protected area. You want to ensure that there's no disturbance from wind, debris, or anything else that could block or prevent rain from entering, like a branch or powerline. Check the forecast for rain. Check your gauge exactly 24 hours later to see how high the water has risen. Now you know how much rain has fallen. Check how closely your measurements compare to official ones by checking the news or online for the rainfall measurements of your area for the day. You can continue measuring for 7 - 14 days or until your curiosity has stopped. If this is an experiment assigned by your teacher, make sure you follow every perimeter and take measurements until the experiment tells you to stop. Try to take your measurements at roughly the same time so that you get a 24-hour reading. Then, dump the rain out between each measurement to start a new measurement for the next day.

Summary: Cut the top off of the bottle. Place pebbles in the bottom. Turn the top of the bottle into a funnel. Create your measuring line. Mark off half-centimeter or half-inch intervals. Place the gauge at an optimal location. Pay attention to the weather. Repeat your measurements.

Memorizing the introduction, key points, and conclusion word-for-word is wise. However, unless your teacher requires it, don't feel like you have to memorize the entire speech verbatim. Reciting a completely memorized speech can feel stiff, so just commit the content to memory well enough that you can explain your ideas clearly and consistently. While it's generally okay to use slightly different phrasing, try to stick to your complete outline as best you can. If you veer off too much or insert too many additional words, you could end up exceeding your time limit. Keep in mind your speaking outline will help you stay focused. As for quotes and statistics, feel free to write them on your notecards for quick reference. Use hand gestures to emphasize key words and ideas, and make natural eye contact to engage the audience. Be sure to switch your gaze every 5 or 10 seconds instead of staring blankly in a single direction. Instead of slouching, stand up tall with your shoulders back. In addition to projecting confidence, good posture will help you breathe deeply to support your voice. Once you've committed the speech to memory, work on making your delivery as engaging as possible. Watch yourself in a mirror or record yourself to make sure you appear confident and natural. Get a second opinion and ask a friend or relative to watch you and offer feedback. Have them point out any spots that dragged or seemed disorganized. Ask if your tone was engaging, if you used body language effectively, and if your volume, pitch, and pacing need any tweaks. Use a stopwatch or cell phone app to time yourself when you practice your speech. Speak clearly and avoid rushing, but work on keeping your speech under the time limit, if your instructor set one. If you keep exceeding the time limit, review your complete sentence outline. Cut any fluff and simplify complicated phrases. If your speech isn't long enough, look for areas that could use more detail or consider adding another section to the body. Just make sure any content you add is relevant. For instance, if your speech on nationalism and World War I is 2 minutes too short, you could add a section about how nationalism manifested in specific countries, including Britain, Germany, Austria-Hungary, and Serbia.

Summary: Write the main points and helpful cues on notecards. Project confidence with eye contact, gestures, and good posture. Practice the speech in a mirror or to a friend. Make sure you stay within the time limit.

If you use an Android device, you can install the Google Opinion Rewards app from the Play Store. This app will send you the occasional marketing survey, and you'll be rewarded Google Play credit for completing them. You can then spend this free Play Store credit on Clash of Clans Gems. Most surveys only take a few seconds to complete, and award between $0.10 and $1.00. This app is an official app developed by Google, and is safe to download and use. The Google Opinion Rewards app is not available for iOS devices. If you aren't already signed in on your device with a Google account, you'll be prompted to sign in. Google accounts are free to create. You won't get many surveys unless you turn on location services. This is because many surveys are based on locations that you have recently visited. Open the Settings app on your device and select "Location." Ensure that "Location" is toggled on at the top of the screen. Allow location access if prompted when opening the Google Opinion Rewards app. You may not have any surveys available immediately when you first start the app, but they should eventually start to appear. You'll get more surveys by visiting businesses and traveling a lot. The answers you give do not affect the value of the reward you will receive. You'll receive a notification on your device when a new survey has become available. It may take a little while, but you'll likely amass a nice amount of Play Credit before you know it. Once you have enough to afford some Gems, open the Gem store in the game and buy a pack you can afford. Make sure your Google Play balance is selected as the payment method during the checkout process.
Summary: Download the Google Opinion Rewards app. Sign into the app with your Google account. Enable location services on your Android device. Complete any available surveys. Continue answering surveys until you've accumulated enough Play Store credit to purchase Gems.
