The shorter the bottles are, the more stable your timer will be. For a more realistic hourglass, try to use bulb-shaped bottles, such as Method or Orangina. Make sure that you take the labels off. Use soap and warm water to clean off any residue. Wipe the bottles clean with rubbing alcohol afterwards. Draw a ring of glue around the top the first cap. Be careful not to get any glue in the middle, or you won't be able to make the hole. Place the second cap on top of the glue. Make sure that the tops of both caps are touching. You should only see the underside/inside of each cap. Use a strong glue, such as super glue or epoxy glue. Regular school glue or hot glue will not be strong enough. You can use an electric drill to do this, or a hammer and nail. Experiment with different hole sizes. The larger the hole is, the faster the sand will flow through. The smaller the hole is, the slower the sand will flow through. If you are a child, ask an adult to help you with this step. Some caps have a plastic disk inside them. This can make drilling the hole difficult. Use a flat screwdriver to pop this disk out before you drill the hole. The only difference is that now, you will have a second cap on top of your bottle. Don't worry about this one just yet. If you use damp sand, the sand will clump up in your bottles. Even if you bought your sand from the store, it might be a good idea to spread it out on a baking sheet, and leave it out in the sun for 1 hour. Try using colored sand. You can find it in the floral section of an arts and crafts shop. Add some fine scrapbooking glitter to your sand to make it look more magical. Plain sand and gold glitter will look great together. White sand and iridescent glitter will also look pretty. If you don't care how long your sand timer takes, fill the bottle two-thirds of the way with sand. If you want your timer to run for a specific amount of time, then time yourself filling the bottle using a stopwatch. For example: If you want your sand timer to last 1 minute, fill the bottle for 1 minute. Keep the sand-filled bottle on the table. Turn the empty bottle upside down. Align the cap with the neck of the sand-filled bottle. Screw the cap unto the bottle until it is tight. Turn your sand timer upside down. The sand should be flowing smoothly from one bottle to the next. If you have a specific amount of time for your timer in mind (such as 1 minute), pull out a stopwatch and stop timing it. Be careful when handling your sand timer. The glue holding the caps together will not be very stable. Hold your timer by the seam/neck. Unscrew the bottles first, and keep the sand-filled one standing upright. If the sand is not flowing smoothly enough, make the hole larger. If the bottom bottle is taking too long to fill, empty out some sand. If the bottom bottle fills too quickly, you will need to add more sand. Once you have made the adjustments, screw the bottles back together. Once you are happy with your timer, you will need to secure the necks together. Get some sturdy tape, such as duct tape, and wrap it tightly around the necks of the bottle. Start at the bottom neck, work your way up past the seam, and finish at the top neck. You may want to do this a few times for extra durability. Turn your timer so that the empty bottle is on the bottom. When the sand flows all the way down, the time is up. Flip your timer over if you'd like to use it again.

One-sentence summary -- Find two, clear plastic bottles that are the same size and shape. Take the caps off, glue them together, and let the glue dry. Punch a hole through the middle of the glued-together caps. Screw the cap onto the first bottle, just like you normally would. Make sure that the sand you are using is very dry. Start filling the second bottle with sand. Screw the empty bottle onto the sand-filled bottle. Test your sand timer. Make any necessary adjustments after the sand has finished flowing. Wrap some tape around the neck seam. Use your timer.

Article: Place the raspberries, sugar, and water in a small saucepan. Heat the ingredients over medium heat, whisking frequently, until the mixture thickens into a sauce. Remove from heat and set aside. Take the cake out of the refrigerator and place it on a serving plate. Remove the aluminum foil from the sides of the pan. Run a knife around the edge of the cake to loosen it from the sides, then unlatch the pan and unwrap it. If you have trouble removing the sides of the springform pan without breaking up the cake, try heating the knife in hot water before running it along the sides. Cut the cake into slices, then drizzle some raspberry topping over each one. Serve the cake with more raspberry topping on the side.
Question: What is a summary of what this article is about?
Make the raspberry topping. Remove the cake from the pan. Serve the cake.
