What makes tattoos so long-lasting is they're so deep â the ink isn't injected into the epidermis (the top layer of skin that you continue to produce and shed throughout your lifetime). Instead, the ink is injected into the dermis, which is the second, deeper layer of skin. Dermis cells are very stable, so the tattoo is practically permanent. Tattoos used to be done manually â that is, the tattoo artist would puncture the skin with a needle and inject the ink by hand. Though this process is still used in some parts of the world, most tattoo shops use a tattoo machine these days.

1 Make sure you gap your plugs to the specified gap, unless the plugs say do not gap. 2  Do not try to change the gap of a plug that says do not gap. 3  Putting spark plug wires back on the wrong plugs will cause a poorly running engine, and may make you think you have bigger problems than you do. If you're having trouble locating the spark plugs, look for the black rubbery wires running around the engine. 2  Follow them to the end and you'll find the spark plugs. 3  Check your car's owner manual for the exact location of the spark plugs and the spark plug size you need.
