In one sentence, describe what the following article is about: Gel ink manufacturers all confess that removing gel ink can be difficult, if not impossible, due to the highly-pigmented nature of the ink. Your best bet is to get the stain out as quickly as possible using an all-purpose cleaner.  Add a small amount of your normal detergent, stain removal gel, or even liquid hand soap directly to the stain, and rinse thoroughly with running water.  Then try to blot out any remaining ink by pressing the fabric between two absorbent cloths, or stacks of napkins or paper towels. Dissolve 1 teaspoon of household ammonia in warm water.  Soak the garment in the ammonia solution for 1 hour.  Rinse thoroughly, then hand-wash with your normal detergent, scrubbing the stain with a soft brush, if needed.  If the stain is responding to this treatment, repeat as needed until the ink is gone, and launder as usual. If the ink is not coming out, continue on to the next step. NEVER mix ammonia with chlorine bleach. Mix 1 cup of rubbing alcohol with cup of vinegar.  Place the garment on a clean dry towel, and apply the solution to the stained area with a rag or a spray bottle until the fabric is thoroughly saturated.  Allow the solution to soak in for at least 5 minutes, then pour a small amount of table salt over the stained area.  Wait 10 more minutes, and then scrub the stain with a soft brush, and rinse with hot water. If this method removed some, but not all of the ink, repeat until the stain is gone. Gel ink formulas differ, and while some simply can't be removed, others may respond to alternative treatment options.  If the above methods didn't work, you can always try the methods for removing ballpoint or rollerball ink.  Just make sure to rinse the garment very thoroughly between experiments to avoid mixing chemicals.  You might get lucky, or you might have to learn to live with your newly-enhanced garment.
Summary: Hand-wash with soap or regular detergent right away. Treat the stain with ammonia. Treat the stain with an alcohol and vinegar solution. Experiment with other methods.

Boil a small pot of water. Pour the water into a ceramic cup. You can put the ball directly in the pot of water, but don't leave it in for more than a couple minutes. Ping pong balls can melt or burn when overheated. The water will heat up the air inside the ping pong ball. This causes the air to expand, popping the ball back into shape. To increase the heat and pressure, use a spoon to push the ball underneath the water. Hold it there for about 20 seconds, or until the ball is fixed. Use the spoon or a pair of kitchen tongs to take out the ball. The water will be too hot to touch with your bare hands. Wrap a tissue or handkerchief around the ball, taping all the edges together to form a little sack. Hang the sack from a nail or clothes hanger until the ball cools, about 5–10 minutes. The ball won't be quite as good as new, but it will be round and usable again. Leaving the ball to cool on a flat surface can cause it to slump and form a flat surface.

Q: In storage, marijuana can sometimes leave a strong odor. In order to combat this odor, try storing your marijuana in an airtight, sealable container. A mason jar, a Tupperware container, or a vacuum-packed bag would work well. This will minimize the odor present in the room where your marijuana is being stored. If you do not have a sealable, airtight container, consider storing your marijuana in a Ziplock bag. A simple sandwich bag can help mask odor caused by marijuana. If you use any device to smoke, such as a pipe, sealing it in a Ziploc bag afterwards can also help mask the odor. Make sure the pipe is cool before storing it in a Ziploc bag to avoid a potential fire hazard. If you're growing marijuana inside your home, the smell can become quite strong. You can purchase a device called a carbon filter to help remove odor from your home.  You can purchase a carbon filter online or at a local greenhouse. For most homegrown marijuana, you'll need a filter with a 6 inch exhaust filter. You can purchase the carbon filter and install it in your closet or in the room where you're growing your plants.  You'll need a fan to accompany your filter. When choosing a fan, make sure your fan has a slightly lower "CFM" rating than your carbon filter. The CFM rating is a rating that measures airflow, and a fan will not work properly in conjunction with a filter if it has a higher CFM rating. For example, if your filter's box says it has a CFM of 300, make sure your fan has a CFM of 300 or slightly lower.  Make sure you are legally allowed to grow marijuana on your property before doing so. In some states, it's legal to grow marijuana for personal use. In other states, you can grow marijuana for yourself or another person to use medicinally. Review your state's regulations before attempting to grow marijuana. Alongside other methods, it's not a bad idea to place some air fresheners around where you store your marijuana. A few plug-in or gel-based air fresheners can aid in removing the unwanted scent of pot lingering in the air. As always, go for air fresheners that have a natural scent to avoid suspicion.
A: Store in airtight containers. Seal in a Ziplock bag. Use a carbon filter if you're growing. Place air fresheners near your weed.

Problem: Article: One jar will be used for making the eucalyptus oil in, and the other for storing it. You can use pint jars, quart jars, or larger jars, depending on how much eucalyptus oil you intend to make.  Make sure your jars are clean and dry, as any water or moisture can result in mold. The jar you use for making the oil can be clear or dark glass. A dark glass jar is best for storing the eucalyptus oil. You will use the same proportion of leaves to oil as you did in the crock pot method - about 4 parts oil to 1 part eucalyptus leaves. Use 1/4 cup of eucalyptus leaves for every cup of oil.  Place the eucalyptus leaves in the jar, followed by a thin layer of sea salt. The salt will help to extract the oil from the leaves. With the handle part of a long spoon, smash the eucalyptus leaves into the bottom of the jar, releasing their natural oils. Allow to steep for at least 2 weeks in the warm sunshine. The longer you allow the mixture to steep, the stronger it will be.  Make sure your jar is tightly sealed, and give it a good shake to stir the leaves together with the oil. Continue to shake the jar every 12 hours or so until the steeping is finished. The spot where you keep your mixture while it's steeping should receive 8-12 hours of direct sunshine per day for maximum benefit. Keep it in an area that's not hidden from site, so that you don't forget to shake it. Hold the strainer or cloth over the open mouth of the jar, and pour the oil into your storage jar.  The strainer will catch the leaves, which you can discard. Wipe down any excess oil from your storage jar with a damp cloth. You can be as creative as you like in designing labels for your homemade essential oils, but you'll definitely want to identify it by type (Eucalyptus Oil) and by the date it was completed.  The oil will be good for approximately 6 months from the time you make it.  If you've included other herbs to your eucalyptus oil, include this on the label. Some popular additions are: Sage, Lavender, Spearmint, or Rosemary. To store oil for a longer time, keep in the refrigerator.
Summary:
Gather two mason jars. Gather eucalyptus leaves, as in preceding steps. Pour the oil over the smashed eucalyptus leaves and salt mix. Strain leaves from oil by pouring through a tea strainer or cheesecloth. Label the eucalyptus oil.
