For this experiment take the bottle halves. Place the bottle upside down in another half of the bottle. Take a piece of cotton and put the cotton in the bottle first. Then pour sand into it. After adding sand pour fine activated charcoal. You can see the making of Homemade ACTIVATED CHARCOAL in the previous video. I’ll give you the link to the video in the description. After making a 1/2 Inch layer of charcoal put 1 inch of gravel layer and then put 2 inches of pebble layer. Repeat the layer-making process in the same manner once again. After this pour dirty water on the top of the bottle. The water we get at the end is free of impurities.
