Eliminating onions' smell

If you don't like the watery-eye-inducing odor when cutting onions, refrigerate the vegetable beforehand.

Flying first class

If you fly first class remember that drinks, including alcoholic ones, are complimentary of the airline.

Flushing cravings

A good way to keep your appetite in check is to swill water to get the previously-eaten food's taste out of your mouth. By removing the leftover taste you will be less inclined to have a second helping if you're not hungry.

PB&J "Bag"

A good way to prevent a messy PB&J is to cover both in-sides of the bread with peanut butter, spread to edge. Be sure to place the jelly in the middle of one side of bread without letting it reach the edge. This way, when the two slices are pressed together the peanut butter will seal the jelly inside.

Regional nickname pronunciation

"Aussie," slang for "Australian," is pronounced with "zz," not "ss." Think "Ozzy Osbourne."

Wicks/Wet Fingers

If you want to extinguish a candle, stick of incense, or any other small flame, by wetting your fingers and pinching the wick, be sure to wet more of the finger than you think you'll need. If you only wet a small portion you may misjudge where the wet spot is when you go to pinch the flame, resulting in a burn.

Jerky Move Tool

In Autodesk's Maya, if the move tool is behaving as though snapping is turned, but it's not, check the tool's preferences (by double clicking on its icon) to see if "discrete move" is turned on. Turning it on will result in the aforementioned jerky movements, turning it off will restore it to normal.

Natural yeast

Yeast, the bacteria that causes bread to rise and alcohol fermentation, grows naturally on the outside of grapes.

Birds/dominance

With a pet bird, be sparing on letting it sit on your shoulder; the highest perch represents psychological dominance. You want to maintain an owner/pet relationship and sitting on your shoulder will make the bird less submissive and more aggressive.

Cotton Kills

Wearing clothes made from cotton is great for hiking, but when it gets wet it can become a major problem. Because cotton absorbs and retains water very well, it can become abrasive leading to blisters and sores. Plus, when the temperature becomes cold, wet cotton will sap your body temperature which can quickly lead to hypothermia.

Earthquake prediction

As of this post, scientists cannot predict earthquakes like they can the weather. Instead, they are limited to evaluating likelihoods of earthquakes in certain areas (ie, an area like Los Angeles is more likely to have an earthquake as it lies on the San Andreas fault, as opposed to Utah which does not rest on any tectonic lines).

Gift card activations

If you've received a gift credit card (ie, Visa) in the mail be sure to read all its accompanying documents. In the case that there is an activation code not printed on the card itself it's most likely on the paper it was attached to. Not reading and discarding that paper would result in the loss of the activation code, which would ultimately cause you to lose your gift money as well.

Band-Aids/Neosporin

If you're using a combination of band-aids (adhesive strips) and neosporin (antibacterial creme) to heal a wound, apply the creme to the cotton of the band-aid first. If you smear the creme on the wound first you'll likely spread it where the adhesive part of the band-aid is supposed to go, preventing it from sticking. Applying creme to the band-aid's cotton prevents this.
