Article: Switch the hammer of the revolver into its half cocked position again. Note that the cylinder should be able to rotate freely at this point. Point the barrel of the gun toward the sky, keeping the entire gun in an upright position. Keep the right side of the gun facing toward you. Do not position any part of your body over the revolver. Carefully pour a properly measured charge of black powder into the chamber closest to the loading cutout. Repeat for each chamber. Use an individual powder measure. Do not pour powder from a large powder flask or can. The exact amount of powder will vary depending on the type of gun. For a .36, use 12 grains of powder. Never exceed 20 grains. For a .44, use 20 to 28 grains of powder. Never exceed 35 to 40 grains. Set a proper size ball or bullet over the opening of the chamber nearest the loading cutout. The ball should be oversized so that it only rests on top and does not enter. Make sure that the ball or bullet has been lightly greased before you load it. Rotate the cylinder of the revolver until the ball sits under the plunger of the loading lever. Unlatch the loading lever and use it to firmly press the ball down until it sits securely and firmly on the powder. Apply smooth, even pressure as you do this. There should be no air in between the powder and ball, but you should not crush the powder as you seat the ball. Also note that a thin outline of lead will be shaved off the ball as you do this. It should be visible at the opening of the chamber. This is a good sign and and indication that the ball is properly fitted. Follow the same steps to load the remaining chambers with a ball or bullet. It is recommended that you only load five chambers of a six-chamber revolver. Keep the hammer rested on the nipple of the unloaded chamber to reduce the risk of an accidental firing. Fill the space above the ball in each cylinder with vegetable grease or bullet lubricant. The use of grease can prevent "chain firing," or accidental secondary discharges. Point the gun down range and place a percussion cap on each loaded chamber. With the completion of this step, the revolver is fully loaded. Make sure that the hammer is still in a half cocked position before doing this.
Question: What is a summary of what this article is about?
Half cock the hammer. Hold the muzzle up. Pour a measured charge into the chamber. Place the ball over a chamber opening. Rotate the cylinder. Seat the bowl using the loading lever. Repeat with the remaining chambers. Apply additional grease. Place a percussion cap on each loaded chamber.

To make your own pH indicator, you will need half a head of red cabbage, a knife, water, a stove, and a medium saucepan. Red cabbage contains a chemical called anthocyanin that changes color based on acidity. By boiling the cabbage, you can make a pH indicator from this chemical and test the acidity of your rain. Adult supervision is recommended for this because you will need to handle a hot stove and a sharp knife. . You want about 2-3 cups of red cabbage cut into small pieces. If you are young, have an adult help you with this step to avoid potential injury. The exact amount of cabbage is not important, so just cut up half of the head of cabbage. Place the chopped cabbage into the saucepan and add enough water to cover the cabbage. Put the saucepan on the stove and bring the water to a full boil. Once the solution boils, turn the heat off and let the water cool to room temperature. Have a parent help with this step to avoid injury when using the stove and working with boiling water. You should notice that the water is now purple. Pour the cabbage and water mixture through a strainer into a bowl. The purple water (the indicator) is currently neutral because the water from your tap is neutral. In the presence of an acid, the indicator turns pink. In the presence of a base, the indicator turns blue. You can refrigerate the solution until you need it. To make sure the indicator is working properly, you can test it using baking soda and vinegar. Put 1 teaspoon (~5 mL) of the cabbage water into two small, clear glasses. Add a teaspoon of vinegar to one glass and a teaspoon of baking soda to the other. Vinegar is acidic, so the water will turn pink. Baking soda is basic, so the water will turn blue. Collect some rainwater in a clean, plastic container. Pour 1 teaspoon of cabbage water into a small, clean glass. Add a teaspoon (~5 mL) of the collected rainwater to the cabbage water. The water should turn pink because all rain is slightly acidic. The deeper the pink, the higher the acidity in your area. This method will not tell you the exact pH of the rain, but will give you an idea of how acidic it is. If you are traveling, you can compare rain from different areas such as different cities, state or province, or even countries and see if the deepness of the pink changes.
