Problem: Article: Caulking guns use specially-designed cartridges to dispense caulk. These look like long cylindrical tubes with a skinny pointed cone or "nose" at one end. Before loading your cartridge, take a knife or a sharp pair of scissors and trim off the very end of this "nose" at about a 45 degree angle to create a small, slanted hole. This hole should be only about 1/8th of an inch in diameter — about the width of a matchstick.  Try to cut your cartridge's tip as conservatively as possible. It's easy to make a small hole bigger, but impossible to make a large hole smaller. Next, use the gun's piercing rod (which is usually a stiff piece of wire attached to the gun) to poke a few holes in the cartridge's membrane through the hole you just cut in the tip. This allows caulk to flow easily out of the cartridge. The more holes you poke, the more easily the caulk will flow. About 4-5 holes is usually sufficient.  Note that some plastic cartridges don't have an internal membrane. If you don't feel any resistance when using the piercing rod, you'll know this is the case. Most caulking guns can be loaded via the following steps:   Push the spring-loaded lever on the gun and hold it down. Pull the rod at rear of the gun (the "pushrod") all the way back while holding the lever down. Insert the cartridge into its slot butt-first, then drop the cartridge's point down into the space in the front of the gun. Make sure the angle of the cut in the point is facing downwards. You may need to turn the cartridge to do this. Finally, twist the pushrod so the notches are facing downward. Pull the trigger a few times until you feel resistance. You're now ready to caulk! To practice, spread out a large piece of newspaper on the floor and hold the point of your caulking gun against it. Pull lightly on the trigger until caulk begins to flow out of the nozzle. When caulk begins to flow out of the gun, move it slowly back while keeping constant pressure on the trigger. Try to make a long, thin, consistent line of caulk without any gaps or thick spots. When you're done, lift the nozzle from the work surface, then twist the pushrod so the notches are in the "up" position and depress the spring-loaded lever. This releases the pressure on the cartridge and stops the flow of caulk.  Don't squeeze too hard when you're applying caulk — this can rupture the cartridge, causing a mess and forcing you to start over. When you're ready to caulk for real, hold the tip of your caulking gun against the space where the wall and the top of the baseboard meet. Keep the hole in the tip flat against the wall (this means you should hold the gun diagonally. Turn the notches in the pushrod downward. Squeeze on the trigger with steady pressure and begin moving the caulk gun along the length of the baseboard as the caulk flows out. Move at a slow, even pace. Continue along the entire length of the baseboard. Treat any spills with a damp rag.  Don't forget to repeat the process outlined in the practice step for stopping the flow of caulk when you're done with your run. When you've caulked one edge of your baseboard, you'll want to smooth the caulk with your finger to ensure the caulk sits in its gap as securely as possible and also to ensure that the caulk has a uniform, smooth appearance. Drag the tip of one finger along the caulk lightly a few feet at a time. As soon as a significant amount of caulk accumulates on your finger, wipe it off with a clean, damp rag. Treat any spills with a separate damp rag.  Don't smooth with too much force. Apply only gentle pressure with your finger. Pressing too hard can scrape the caulk from the wall entirely. Next, repeat the caulking process for the bottom length of the baseboard. Keep firm but steady pressure on the trigger of the caulking gun to dispense caulk along the bottom edge of the baseboard. Caulking the bottoms of the baseboards after you've finished smoothing the caulk on the top of the baseboard ensures that leftover caulk from the top won't spill onto your work below.  When finished, smooth over the caulk with your finger as described above. When you've caulked and smoothed both edges of a length of baseboard to your satisfaction, it's time to pull your tape up. Be sure to do this while the caulk is still fresh. If the caulk dries before you pull up the tape, you'll end up pulling the caulk from the baseboard along with the tape and will have to repeat your work. Grab one end of your length of tape and pull it gently away from the surface at a forty five degree angle. Proceed slowly and delicately along the entire length of tape. Repeat for the second length of tape.   If you used multiple lengths of tape for a single surface, pull the tape from the wall in the same direction that you laid it. For instance, if you laid three overlapping pieces of tape from left to right, pull the tape from left to right as well. Handle the tape with care — the leftover caulk can stick to (and stain) clothing with ease.
Summary: Cut a hole into your caulk cartridge's point. Pierce the cartridge's inner membrane. Load a cartridge into your caulking gun. If inexperienced with a caulk gun, practice first. Caulk the tops of the baseboards. Smooth the caulk with your finger. Caulk the bottoms of the baseboards. Pull your masking tape before the caulk dries.

In one sentence, describe what the following article is about: Take an 11 by 7 inch baking pan (approximately 28 by 18 centimeters). Spray with a non-stick baking spray. Then, pour your brownie batter into the pan using a spatula or spoon. Brownies should be baked at 350 degrees Fahrenheit (about 178 degrees Celsius). The brownies should bake for about 35 minutes. Check to make sure your brownies are done before removing them from the oven. To do this, stick a toothpick in the center of the brownies. It should come out clean. If there is batter on it, bake the brownies for a few more minutes. After removing them from the oven, set the brownies aside for an hour or so. You want them to cool completely before proceeding. There is no precise size to cut your brownie bites. It depends on personal preference. Use a knife to cut the brownies into bite-sized portions. You can do this by cutting vertical lines through the brownies, followed by horizontal lines. For the cleanest cuts, use a cold knife. You can put a butter knife in the refrigerator for an hour, for example, and then use it to cut the brownies. Set your brownie bits in a refrigerator. You should let them chill for at least an hour. This way, they will be solid enough to dip in your chocolate mixture. As the brownie bits will not be in the fridge for long, it's okay to put them in uncovered. However, you can put aluminum or plastic covering over the brownie bits if you want.
Summary:
Prepare your baking pan. Bake your brownies. Allow your brownies to cool. Cut your brownies. Chill your brownie bites.
