Summarize this article in one sentence.
Take one of your strips of paper and drop it into the pitcher of acid. Use a glass stirring rod to poke your paper in the water until it is completely submerged. You can do all your sheets at the same, so keep adding and submerging the sheets with the glass rod until you have added all your paper. After you have added your last sheet, wait 15-20 minutes for the paper to fully absorb the acid. By the end of the wait, tissue paper or regular paper will be off-white, while toilet paper will be slightly brown. While you are waiting for the paper to soak, fill a wide 1 liter (0.26 US gal) (4.2 cup) beaker or pitcher halfway up with water. Make sure that the beaker is wide enough to fit the papers. Place the beaker of water next to the pitcher of acid. Use a pair of forceps or tongs to lift up one of the pieces of paper out of the acid. Keep the paper poised above the pitcher of acid until it stops dripping. Once the paper stops dripping, carefully drop the paper into the beaker of water. Repeat this process for each of your strips of paper, making sure that they stop dripping before you transfer them. You are now done with the acids. Neutralize the acids by pouring baking soda into the beaker of acid, waiting until the bubbling stops. Then turn on the water and pour the neutralized acid down the drain. Run the water for a few more seconds, then turn it off. Leave the pieces of paper in the water bath for about five minutes, using the glass stirrer to occasionally stir the papers. If you are using toilet paper, you should see the paper turn from brown to off-white. Bring the water beaker to the sink. It’s not necessary to work under the fume hood anymore, as you have finished working with the acids. Carefully pour the water out of the beaker, using the glass stirrer to push back the paper so it doesn’t escape from the beaker. After you empty out the water, turn on the sink and pour about the same amount of lukewarm water back into the beaker. What you are essentially doing is washing the paper to get off excess acid. Repeat the process of draining the water, then filling the beaker back up two or three more times. This will effectively flush the paper. Take the papers out of the water bath one by one with a pair of tongs, pausing over the beaker until they finish dripping. Then place the side of the papers by side on a folded sheet of paper towel. Leave the paper on the sheet of paper towel to dry overnight, or for at least 8 hours. Make sure that they aren’t overlapping so that they can dry quicker. After the paper has dried, fill a 1 liter (0.26 US gal) (4.2 cup) beaker with a 1 ML solution of sodium bicarbonate. Then place each piece of paper as you did with the water bath in the sodium bicarbonate.  If you notice bubbling, take the beaker to the sink and pour out the sodium bicarbonate, holding the papers back with the glass stirrer. Then add water as you did before, adding it and emptying a few times. Wait for the paper to thoroughly dry, either overnight or for 8 hours. Fill pitcher with enough ethanol to submerge the papers, then add the papers as you did for the sodium bicarbonate. Let them soak in the ethanol for 15-20 minutes, then take them out, waiting for them to stop dripping, and place them on a fresh folded sheet of paper towel.
Add and submerge the paper. Wait for 15-20 minutes. Pour water into a 1 liter (0.26 US gal) (4.2 cup) beaker. Transfer the paper to a water bath. Soak the paper for about 5 minutes. Pour out the water and fill up the beaker. Repeat the washing process several times. Place the paper on a paper towel. Place the paper in sodium bicarbonate. Place the paper in ethanol.
