Snorkeling

Snorkeling (British and Commonwealth English spelling: snorkelling) is the practice of swimming on or through a body of water while equipped with a diving mask, a shaped tube called a snorkel, and usually fins. In cooler waters, a wetsuit may also be worn. Use of this equipment allows the snorkeler to observe underwater attractions for extended periods with relatively little effort and to breathe while face-down at the surface.

Snorkeling is a popular recreational activity, particularly at tropical resort locations. The primary appeal is the opportunity to observe underwater life in a natural setting without the complicated equipment and training required for scuba diving. It appeals to all ages because of how little effort there is, and without the exhaled bubbles of scuba-diving equipment. It is the basis of the two surface disciplines of the underwater sport of finswimming.

Snorkeling is also used by scuba divers when on the surface, in underwater sports such as underwater hockey and underwater rugby, and as part of water-based searches conducted by search and rescue teams.

Shotgunning

Shotgunning is a means of consuming a beverage, particularly beer, very quickly by punching a hole in the side of the can, near the bottom, placing the mouth over the hole, and pulling the tab to open the top. The beer quickly drains, and is quickly consumed.

A related technique, strawpedoing or snorkeling, is used for containers not easily punctured such as a glass bottle. A straw is inserted into the bottle to similar effect.

The technique increases beverage delivery since the extra hole allows the liquid to leave while air enters simultaneously through the main hole. The bottleneck, created where air entering the container must travel through the same orifice as liquid leaving, is removed.

Technique

To shotgun a beverage, a small hole is punched in the side of the can, close to the bottom. In order to prevent the liquid from spilling out while the cut is made, the can is held horizontally, tilted slightly, and the hole is made in the resulting air pocket. The hole can be made with any sharp object. Typically a key, bottle opener, pen, knife, other sharp instrument is used. The drinker then places their mouth over the hole while rotating the can straight up. When the can's tab is pulled, the liquid will quickly drain through the hole into the drinker's mouth.

Fire engine

A fire engine (also known in some territories as a fire apparatus, fire truck, or fire appliance) is a vehicle designed primarily for firefighting operations. In addition, many fire departments often employ their vehicles for various other uses including emergency medical services and rescue purposes. The terms "fire engine" and "fire truck" are often used interchangeably but in North America represent different types of vehicles.

The primary purposes of a fire engine include transporting firefighters to an incident scene, providing water with which to fight a fire, and carrying other equipment needed by the firefighters. A typical modern vehicle will carry tools for a wide range of firefighting and rescue tasks, with common equipment including ladders, a self-contained breathing apparatus, ventilating equipment, first aid kits, and hydraulic rescue tools.

Many fire vehicles are based on standard vehicle models (although some parts may be upgraded to cope with the demands of the vehicle's usage). They are normally fitted with audible and visual warnings, as well as communication equipment such as a two-way radios and mobile computer technology.
