Tea tree oil is a natural essential oil with effective antibacterial properties. It is also an astringent, which means it can help to dry out the blister. Use a q-tip to dab a little of the oil onto a drained or lanced blister once a day, before applying a fresh bandage. Apply cider vinegar is a traditional home remedy for many minor ailments, including blisters. It can be used to ward off infection, thanks to its antibacterial properties. Apple cider vinegar can sting a lot, so you may want to dilute it to half strength with water before using a q-tip to dab it on the blister. Aloe vera is a plant whose sap has soothing and healing properties. It is a natural anti-inflammatory and moisturizer, making it a great option for blisters caused by burns. To use, break off a leaf from the plant and rub the clear, gel-like sap over and around the blister. This is especially useful once the blister has popped, as it will speed up the healing process. Green tea has natural anti-inflammatory properties, so soaking the blistered skin in a bowl or basin of cooled green tea can help to soothe swollen or inflamed skin around the blister. Vitamin E allows the skin to heal faster and helps to prevent scarring. It can be found in both oil and cream form at the drugstore. Simply smooth a little over the blistered skin each day to promote healing. Chamomile has soothing qualities and can help to ease the pain of a swollen blister. Make a strong cup of chamomile tea, allowing it to brew for five to six minutes. Once it has cooled slightly, dip a clean washcloth into the tea until soaked, then wring out the excess moisture. Press this warm compress against the blister for about ten minutes, or until the pain subsides. Epsom salts help to dry out an unpopped blister and encourage it to drain. Simply dissolve some Epsom salts in a hot bath and allow the blister to soak. Be careful though, once the blister has burst the Epsom salts will sting.

What you hear is often as important as what you see when dealing with an unruly amp. Now that you know your amp isn't completely busted, remove the sound wires connecting to speakers and other devices. If the noise stops, then you know you have a wiring problem. Hissing and crackling are often easy to fix by rearranging the wires or getting complimentary speakers. If the noise doesn't stop, then you probably have a faulty amp to replace. Every device has an amperage rating that indicates what current strength it can handle. Use speakers with a similar or slightly higher rating than the amp. The wrong rating, whether it is too low or too high, means your system won't work the way you want it to. If the amp has a much lower rating than the other devices, it won't send enough sound to the speakers. You may hear a lot of static or get a low-volume sound. Higher amp ratings lead to a louder, stronger sound quality. However, if the amps are more powerful than the speakers, your speakers could burn out much quicker than usual. Hissing coming from your speakers is often a sign that the wires aren't positioned correctly. It's an easy fix, but it's often a little annoying and time-consuming. Go back through the wires, separating the speaker wires from the amp wires. Tuck the speaker wires into safe areas, taping them down or using plastic ties to keep them in place. The positive and negative wires are a common problem. When they touch, they cause the system to go silent and lose power. This doesn't usually harm your devices. You can test for wire problems by moving the wires apart while the speakers and amplifier are on. Don't touch any exposed ends or active power sources like a car battery or wall outlet. Listen for the sound to come back on as you separate the wires. Loose speakers and subwoofers rattle in their cases as sound passes through them. Make sure your devices fit securely in storage spots or leave them out in the open so they aren't bumping against things. Keep them well-mounted so they don't move at all. If your devices have screws holding them in place, tighten the screws to prevent them from rattling. Whooshing sounds happen when air gets pushed out of a speaker or subwoofer as it vibrates. You can fix it by mounting the device to stabilize it or by turning down its settings to make it rattle less. If your amp turns on but no sound comes out of the speakers, your overall setup may be the problem. Not all speakers are compatible with an amp. If your amp is still alive, it will respond when you connect it to speakers and other devices in good condition. Turn up the volume to see if anything changes. Fixing any wiring and mounting issues solves sound problems if your amp still works. Radio silence from a good pair of speakers is a good sign that your amp needs to be replaced.

One-sentence summary -- Test the sound by unplugging the sound cables or colored RCA wires. Compare the amp's power ratings with the speakers and subwoofers. Reroute speakers wires so they aren't touching one another. Stabilize the speaker enclosure to prevent rattling. Connect the amp to a working pair of speakers.

Playing telephone in teams can add a fun competitive edge to the game. Teams will each play the game in same manner, with one person starting the game off and the players whispering it down the line. However, one player is chosen to whisper the same word to both teams. The goal is to see which team can end the game with the word being closest to the original. Words that are closer will generally sound more alike or be a variation of the original word. Words that are farther apart from the original will generally have wildly different sounds and meanings. For example, you may start with the word "benevolence". One team ends the game thinking that the word was "beneficent", while the other team got "detriment". In this case, the team who said "beneficent" would be closer to the original word and win the round. In this version, players are required to make changes. Even if you hear the phrase correctly, you must add one or two differences. This will result in huge changes to the original phrase the game started with. For example: If you started out with "Mary had two white cats," the next person might say: "Mary had two black dogs." The third person might say: "Mary had one black-and-white dog." If you are finding that your team is able to keep the word or phrase close to the original, you can try making the game harder. Try picking new words or phrases that are more difficult to hear correctly. Keep some of these tips in mind when trying to make the game of telephone a bit more difficult: Pick longer words or phrases. The more you say, the harder it will be to pass on to the next person. You might try using "Squirreled" or "Can you can a can as a canner can can a can?". Pick words that aren't often used. For example, "magnanimous" isn't said often and may cause players to mishear it. Use random words that don't have context. For example using "tower, nose, zircon" would make it much more difficult to guess what was said without the context that normal phrases would have.
