Summarize the following:
The needle will have a cap on it when you push it onto the end of the syringe, or should if it's a fresh, clean needle. Push the needle down on the syringe so the needle stays on and won't come off. Take the cap off the needle and have it ready to draw fluid into the syringe. You won't be able to get medication into the syringe if you have the cap still placed over the needle. The aluminum cap protects the opening of the bottle and keeps the liquid from leaking out, such as if the bottle is tipped on its side or upside down. Use your fingernails to remove the cap. Never use a knife or sharp object because you will compromise the rubber cap and invite contamination. Before you do so, draw the same amount of air into the syringe as you want to draw from the bottle. This makes it easier for you to draw in the contents. Then, you can poke the needle into the rubber cap. The rubber cap will act as a vacuum to keep air out of the bottle, and when the needle is pushed through, this vacuum will not be disrupted. After you have pushed the air in your syringe into the bottle, raise the bottle up so that it is almost vertical above the syringe, and slowly pull back on the plunger. Draw the fluid into the syringe up to the desired amount. It's important to raise the bottle above the syringe to allow gravity to draw the fluid in, and so that you're not drawing in air instead. Lowering the bottle moves the liquid to the bottom (via gravity) and introduces the "air" component of the bottle. Removing the needle then ensures that liquid won't drip out. Store the bottle in a place where it's cool and dry and won't get damaged, like in a cooler or toolbox meant for storing your cattle medicating equipment. Flick your finger against the barrel for any bubbles that don't automatically float up. Slowly and carefully push the plunger to eject the air bubbles. This especially important if you are going to administer IM or IV injections.

summary: Take a syringe and cap it with a needle. Remove the needle cap. Take a new bottle and remove the aluminum cap. Poke the needle through the rubber cap. Draw the medication into the syringe. Lower the bottle and slowly remove the needle. Place the bottle upright in a safe place for future use. Point the needle upwards to allow any air bubbles present to float to the top.

You're going to soak your item of clothing for a while, so make sure that the bowl is big and deep enough to keep your clothing fully submerged for a long period of time. Place the stained area at the lowest point in the bowl or sink so that it can fully soak when you add your vinegar. White vinegar is the least likely to damage colored clothing. In a large bowl, combine 1 part white vinegar with 1 part water and mix it with a large spoon. Pour your mixture over the stain so that it is fully submerged in your mixture. About 13 cup (79mL) of each ingredient will be enough for 1 shirt or pair of pants as long as this will cover the stain completely. Allow your clothing to soak in the vinegar solution for at least 30 minutes before throwing it in with your sorted laundry for a standard wash. If you notice that the stain is still there after you've washed it, repeat this process.

summary: Place your item of clothing in a sink or large bowl, inside out. Fill a bowl with white vinegar and water and pour it over the stain. Let your clothing soak for 30 minutes before washing it.

It doesn't matter if it's an aluminum or rubber balloon. They're sold at party centers or you could rent a helium tank to fill up your own balloons for a special event. You'll know a balloon is filled with helium if it floats. Helium is lighter than air, so it naturally rises. If a balloon stays down near the ground, it doesn't have helium in it. If you don't have a safety pin, a pushpin or sewing needle will work just the same. Use the pin to prick the balloon and create a really small hole, and then squeeze the hole shut with your fingers to keep the helium from escaping until you're ready to inhale. If the balloon is inflated but not knotted, you don't need to poke a hole in it. You can simply suck the air directly from the opening. Don't just hold the helium in your mouthbreathe it in like you would a normal breath of air. Just 3-4 seconds should be enough to fill your lungs with helium. It helps to exhale fully before inhaling so that you can get as much helium into your lungs at once as possible. Helium doesn't have an odor, taste, or smell, so you really won't be able to tell that you're breathing in an element different from oxygen until you try to speak. As soon as you've finished inhaling, start talking! The helium-effect will only last for 5 seconds or so, so don't wait too long. What you say is totally up to you! Have fun and come up with unique phrases or just repeat your name over and over again to hear how you sound. If you suck too much helium at once or for too long of a period of time, you can hurt yourself. So between each inhalation of helium, take a few minutes to breathe normally.
summary: Get a balloon filled with helium. Poke a small hole near the balloon's knot with a safety pin. Put your mouth over the hole and inhale while squeezing the balloon. Say something funny to hear how the helium affected your voice. Wait 2-3 minutes between each helium-inhale to rebalance your oxygen.
