Raingutter Regatta
The raingutter regatta is a racing event for Cub Scouts in the Boy Scouts of America that is the sailboat equivalent of the pinewood derby. The sailboat kit consists of a seven-inch (178 mm) long balsa wood hull, a -inch mast, plastic sail, plastic rudder, and metal keel. Within the basic design rules, Scouts are free to paint and decorate their sailboats as they choose. Modifications for speed include the placement of the keel and rudder and the size, shape and location of the sail. A catamaran is an exceptionally fast design, although this modification is not allowed in all races. The boats are raced in a standard rain gutter that is ten feet long, placed on a table or saw horses, and filled to the top with water. The boats are propelled by blowing on the sail, either directly or through a drinking straw; the boat cannot be touched with hands or the straw. The first boat to reach the end of the gutter is the winner. The overall winner is determined by an elimination sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Saw Horse
In woodworking, a saw-horse or sawhorse (saw-buck, trestle, buck) is a trestle structure used to support a board or plank for sawing. A pair of sawhorses can support a plank, forming a scaffold. In certain circles, it is also known as a ''mule'' and a short sawhorse is known as a pony. The names come from the shape of the frame, which resembles a horse. A sawhorse may also be a rack for supporting logs for sawing, known in the US as a sawbuck. The sawhorse may be designed to fold for storage. A sawhorse with a wide top is particularly useful to support a board for sawing or as a field workbench, and is more useful as a single, but also more difficult to store. A sawhorse can also be used as the base for a portable work table by placing a sheet of plywood or even a door across two sawhorses. If the sawhorses are strong enough, the portable table can be used as a platform for tools like a table saw, although with caution if the top is not secured to the sawhorses. In boatmak ...

Bicycle Rodeo
A bicycle rodeo is a clinic to teach children the skills and precautions to ride a bicycle safely. Origin In the United States, Kiwanis clubs originated the idea of teaching bicycle safety to organized groups of children. They set up bicycle lectures which then became bicycle seminars. Eventually, a more hands on approach was used to teach the children and the term bicycle rodeo was adopted. This name is much more attractive to children and helped the events to grow in popularity. In Denmark a similar concept called ''mobil cykelbanes'' (mobile bicycle playgrounds) was introduced about 2012. Organizers Bicycle rodeos are usually run by local police departments. Police Chief Rosanne M. Sizer of the Portland, Oregon Police Department said, "It's important that our children understand bicycle safety. This is an opportunity for area youth to learn important skills and in the process get to know some of our bicycle, traffic, and reserve officers." The Kiwanis clubs still run rodeo ...

Radio-controlled Boat
A radio-controlled boat is a boat or ship model controlled remotely with radio control equipment. Type Fun sport Electric sport boats are the most common type of boat amongst casual hobbyists. Hobby-quality boat speed generally start at around 20 mph and go up from there, and can be just as fast or faster than their internal-combustion counterparts, with the latest in lithium polymer and brushless motor technology. Ready-to-run speedboats from AquaCraft, ProBoat and OffshoreElectrics can reach speeds over 40 mph out of the box and with modifications can reach well into the 50-60 mph range. These types of boats are referred to as "hobby grade" and can be found only at hobby shops and retailers. "Toy grade" boats which are obtained through mass consumer retailers, are generally much slower and their maximum speeds are usually less than 15 mph. Scale Scale boats are replicas of full-size boats. They are to scale of the full sized ones. They can be sm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Model
Ship models or model ships are scale models of ships. They can range in size from 1/6000 scale wargaming miniatures to large vessels capable of holding people. Ship modeling is a craft as old as shipbuilding itself, stretching back to ancient times when water transport was first developed. History Ancient Mediterranean Ancient ship and boat models have been discovered throughout the Mediterranean, especially from ancient Greece, Egypt, and Phoenicia. These models provide archaeologists with valuable information regarding seafaring technology and the sociological and economic importance of seafaring. In spite of how helpful ancient boat and ship models are to archaeologists, they are not always easily or correctly interpreted due to artists’ mistakes, ambiguity in the model design, and wear and tear over the centuries. Ships "were among the most technologically complex mechanisms of the ancient world." Ships made far-flung travel and trade more comfortable and economic ...

Model Yachting
Model yachting is the pastime of building and racing model yachts. It has always been customary for ship-builders to make a miniature model of the vessel under construction, which is in every respect a copy of the original on a small scale, whether steamship or sailing ship. There are fine collections to be seen at both general interest museums such as the Victoria and Albert Museum in London and at many specialized maritime museums worldwide. Many of these models are of exquisite workmanship, every rope, pulley or portion of the engine being faithfully reproduced. In the case of sailing yachts, these models were often pitted against each other on small bodies of water, and hence arose the modern pastime. It was soon seen that elaborate fittings and complicated rigging were a detriment to rapid handling, and that, on account of the comparatively stronger winds in which models were sailed, they needed a greater draught. For these reasons modern model yachts, which usually have fin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kon-Tiki (Scouting Event)
Kon-Tiki refers to Scout and Guide raft building competitions held by Scouts South Africa and Scouts Australia. Named after Thor Heyerdahl's Kon-Tiki expedition of 1947, teams of Scouts and Guides age 11 to 17 compete to build and live on a raft for a weekend. Support crews compete in other events while the raft is afloat. South African events The Cape Town competition is held at the Sea Scout Base on the banks of Zandvlei, and was first held in the early 1980s. The event starts on the Friday afternoon with teams arriving and starting construction of the raft. The building criteria are very strict and judging takes place continuously until the raft launch on the Saturday at 2 pm. Much of the judging is related to safety. The Gauteng competition is held at Arrowe Park in Benoni, Gauteng (previous events held at Murray Park, Springs). The first event was held in 1985 at Murray Park. The competition is run in a very similar fashion to the Cape Town one, with the exception that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Derby
The space derby was a racing event for Cub Scouts in the Boy Scouts of America that is similar to the pinewood derby car race. Cub Scouts (the young-age division of the Boy Scouts) race miniature balsa wood gliders that are propelled by a rubber band and propeller. During the 1960s, this was also known as the "rocket derby". Construction The space derby kit consisted of a balsa wood block, propeller assembly, rubber bands, plastic sheet (for fins), and a mounting bracket. The wood block came out of the box with a drilled out center hole. The block was carved into the desired shape, sanded and painted. The mounting bracket and fins could be added either before or after painting. The rubber band was inserted through the center hole with one end on the propeller and the other held in a cross-piece at the rear. Race The completed gliders were wound up with as many as 100 or more turns on the propeller and suspended on a string from a separate bracket with the propeller held in plac ...

Independent Scout And Scout-like Organizations In The United States
Youth organizations in the United States are of many different types. The largest is the government run 4-H program, followed by the federally chartered but private Scouting movement groups: the Boy Scouts of America (BSA) and the Girl Scouts of the USA (GSUSA). Another somewhat smaller but co-ed Scouting derived group is Camp Fire. Other youth groups are religious youth ministries such as the evangelical Christian Awana, Seventh-day Adventist Pathfinders, and Assemblies of God Royal Rangers. Smaller Scout-like groups include the Christian Trail Life USA for boys, American Heritage Girls for girls, the non-denominational co-ed Navigators USA and Baden-Powell Service Association, and pagan but non-discriminatory SpiralScouts International. There are also two types of Masonic Youth groups called International Order of the Rainbow for Girls (IORG or just referred to as Rainbow), and Job's Daughters International (JDI). Both of these organizations have a background in the Christ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double-elimination Tournament
A double-elimination tournament is a type of elimination tournament competition in which a participant ceases to be eligible to win the tournament's championship upon having lost ''two'' games or matches. It stands in contrast to a single-elimination tournament, in which only ''one'' defeat results in elimination. One method of arranging a double-elimination tournament is to break the competitors into two sets of brackets, the ''winners' bracket'' and ''losers' bracket'' (''W'' and ''L'' brackets for short; also referred to as ''championship bracket'' and ''elimination bracket'', ''upper bracket'' and ''lower bracket'', or ''main bracket'' and ''repechage'') after the first round. The first-round winners proceed into the W bracket and the losers proceed into the L bracket. The W bracket is conducted in the same manner as a single-elimination tournament, except that the losers of each round "drop down" into the L bracket. Another method of double-elimination tournament management i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drinking Straw
A drinking straw is a utensil that is intended to carry the contents of a beverage to one's mouth. Straws are commonly made from plastics but environmental concerns and new regulation have led to rise in reusable and biodegradable straws. These straws are often made of silicone, cardboard, or metal. A straw is used by placing one end in one's mouth and the other in a beverage. By employing suction, the air pressure in one's mouth drops causing atmospheric pressure to force the liquid through the straw and into the mouth. Drinking straws can be straight or have an angle-adjustable bellows segment. Drinking straws have historically been intended as a single-use product and several countries, regions, and municipalities have banned single-use plastic straws to reduce plastic pollution. Additionally, some companies have even voluntarily banned or reduced the number of plastic straws distributed from their premises. History Early examples The first known straws were made by the ...

Rain Gutter
A rain gutter, eavestrough, eaves-shoot or surface water collection channel is a component of a water discharge system for a building. It is necessary to prevent water dripping or flowing off roofs in an uncontrolled manner for several reasons: to prevent it damaging the walls, drenching persons standing below or entering the building, and to direct the water to a suitable disposal site where it will not damage the foundations of the building. In the case of a flat roof, removal of water is essential to prevent water ingress and to prevent a build-up of excessive weight. Water from a pitched roof flows down into a valley gutter, a parapet gutter or an eaves gutter. An ''eaves gutter'' is also known as an ''eavestrough'' (especially in Canada), ''rhone'' (Scotland), ''eaves-shoot'' (Ireland) ''eaves channel,'' ''dripster'', ''guttering'', ''rainspouting'' or simply as a ''gutter''. The word ''gutter'' derives from Latin ''gutta'' (noun), meaning "a droplet". Guttering in its ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
