Bed

A bed is a large piece of furniture (or a location) used as a place to sleep, relax, or engage in sexual relations.

Most modern beds consist of a mattress on a bed frame, with the mattress resting either on a solid base, often wooden slats, or a sprung base. In North America many beds include a box spring inner-sprung base, a large mattress-sized box containing wood and springs that provide additional support and suspension for the mattress.

Most beds have a headboard for resting against, with others also having side rails and footboards (or "footers").

"Headboard only" beds often incorporate a dust ruffle, bed skirt, or valance sheet to hide the bed frame.

For greater head support, most people use a pillow, placed at the top of a mattress. Also used is some form of covering blanket to insulate the sleeper, often bed sheets, a quilt, or a duvet, collectively referred to as bedding. Bedding is the removable non-furniture portion of a sleeping environment. A bed can be thought of as a body, and the bedding its clothing.

Also, some people prefer to dispense with the box spring and bed frame, and replace it with a platform bed style. This is more common in Europe, Australia and Japan.

Toast

Toast is bread that has been browned by exposure to radiant heat. This browning reaction is known as the Maillard reaction. Toasting warms the bread and makes it firmer, so it holds toppings more securely. Toasting is a common method of making stale bread more palatable.

In a modern kitchen, the usual method of toasting bread is by the use of a toaster, an electrical appliance made for that purpose. To use a modern toaster, sliced bread is placed into the narrow slots on the top of the toaster, the toaster is tuned to the correct setting (some may have more elaborate settings than others) and a lever on the side is pushed down.

Contact Lenses

A contact lens (also known simply as contacts for a pair) is a corrective, cosmetic, or therapeutic lens usually placed on the cornea of the eye. Leonardo da Vinci is credited with describing and sketching the first ideas for contact lenses in 1508, but it was more than 300 years later before contact lenses were actually fabricated and worn on the eye. Rigid ones were produced and marketed first. Modern soft contact lenses were invented by the Czech chemist Otto Wichterle and his assistant Drahoslav Lím, who also invented the first gel used for their production.

Paper

Paper is a thin material mainly used for writing upon, printing upon, drawing or for packaging. It is produced by pressing together moist fibers, typically cellulose pulp derived from wood, rags or grasses, and drying them into flexible sheets.

Paper is a versatile material with many uses. Whilst the most common is for writing and printing upon, it is also widely used as a packaging material, in many cleaning products, in a number of industrial and construction processes, and even as a food ingredient – particularly in Asian cultures.

Paper, and the pulp papermaking process, was said to be developed in China during the early 2nd century AD by the Han court eunuch Cai Lun, although the earliest archaeological fragments of paper derive from the 2nd century BC in China.

Alarm Clock

An alarm clock is a clock that is designed to make a loud sound at a specific time. The primary use of these clocks is to awaken people from their night's sleep or short naps; they are sometimes used for other reminders as well. To stop the sound, a button or handle on the clock is pressed; but most clocks automatically stop the alarm sound if left unattended long enough. A classic analog alarm clock has an extrahand or inset dial that is used to specify the time at which to activate the alarm.

Traditional mechanical alarm clocks have one or two bells that ring by means of a mainspring that drives a gear that propels a hammer back and forth between the two bells or between the interior sides of a single bell. In some models, the back encasement of the clock itself acts as the bell. In an electric bell-style alarm clock, the bell is rung by an electromagnetic circuit and armature that turns the circuit on and off repeatedly.

Digital alarm clocks can make other noises. Simple battery-powered alarm clocks make a loud buzzing or beeping sound to wake a sleeper, while novelty alarm clocks can speak, laugh, sing, or play sounds from nature.
