SLIDE GUITAR: This is also known as a bottleneck guitar. It is usually, but not always, played in the upright position. It is typically a standard guitar, but instead of fingers, a player uses something called a bottleneck with the left hand while strumming with the right. The "bottle-neck" is also called a slide and is analogous to the steel bar used on the lap steel guitar or the pedal steel guitar. There are many different kinds of bottlenecks that players use, ranging from metal tubes, to glass tubes, to slides, to socket wrenches, to lipstick holders (!), to actual broken necks of bottles!! The "bottle-neck" is slid along the strings to change the pitch. This technique produces glissandos (slurs or slides) and can be quite similiar sounding to a steel guitar.
