Problem: Article: Use kitchen shears or a heavy cleaver to cut the toenails off the end of each chicken foot. If desired, you could also separate the palm of the foot from the connecting leg bone by cutting them apart at the joint. Both parts can then be prepared and cooked in the same manner. Doing this can make it easier to fry the chicken feet, but it will also change their distinctive appearance. Stir 1 Tbsp (15 ml) of salt into 1 qt (1 L) of cold water. Dunk the chicken feet in the salt water and scrub them clean using your fingers.  Rub the feet together while submerged to help scrub off any dirt or debris. Peel away any scaly, yellow outer skin. If you cannot pick away these spots, you can use kitchen shears to cut them away. Remove the chicken feet from the salt water and rinse well under cool, running water. Drain and dry the feet completely using clean paper towels.  It's very important to completely dry the feet after rinsing them. If excess water remains, you may encounter more splattering when you start frying the feet. After drying the feet, set them aside on a clean plate while you prepare the frying oil.
Summary: Clip off the nails. Wash the feet in salt water. Rinse and dry thoroughly.

This may include keyboard, mouse, network cable and speakers. It will be connected to almost every component inside the computer case and will look something like this: Unscrew the mounting screws on the back of the case which hold the power supply in its housing.  Place the screws in a handy location. This is usually a simple process, but if there is little room in your PC, it may be necessary to remove other components to get the power supply out. If you don't feel comfortable removing other components, replace the mounting screws and enlist the help of a PC expert before continuing. Do not try to yank a power supply out by force.

SUMMARY: Familiarize yourself with proper ESD procedures. Disconnect all external connectors (including the power cord) from the machine. Identify the power supply unit. Remove the case cover. Gently remove the old power supply from the case.

An allergic reaction is a medical emergency. Call 911 or seek medical attention the fastest way possible. Do not attempt to drive yourself to a hospital. If you think you are having an allergic reaction from your eye drops, rinse your eyes with an eyewash product if one is available.  If you do not have an eyewash product, then use regular water to flush the eye drop solution out of your eyes to prevent further absorption.  Tilt your head to the side, hold your eye open, and allow clean water to flush the eye drop solution from your eye.
Summary: Contact your doctor if you have unexpected symptoms. Monitor your symptoms. Watch for an allergic reaction. Rinse your eyes.
