Mexican Jumping Beans
Mexican jumping beans (also known as ' in Spanish) are seed pods that have been inhabited by the larva of a small moth ('' Cydia saltitans'') and are native to Mexico. The "bean" is usually tan to brown. They are from the shrub '' Sebastiania pavoniana'', often also referred to as "jumping bean". However, they are not related to actual beans ( legume plants), but rather to spurges. The beans are considered non-toxic but are not generally eaten. In the spring, when the shrub is flowering, moths lay their eggs on the shrub’s hanging seedpods. When the eggs hatch, tiny larvae bore into the immature green pods and begin to devour the seeds. The pods ripen, fall to the ground and separate into three smaller segments, and those segments are called Mexican jumping beans. As the tiny larvae inside curl up and uncurl, they hit the capsule’s wall with their heads – and the bean jumps. It’s been observed that they move more as temperatures rise, the larva eats away the inside of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jumping Beans 12
Jumping or leaping is a form of locomotion or movement in which an organism or non-living (e.g., robotic) mechanical system propels itself through the air along a ballistic trajectory. Jumping can be distinguished from running, galloping and other gaits where the entire body is temporarily airborne, by the relatively long duration of the aerial phase and high angle of initial launch. Some animals, such as the kangaroo, employ jumping (commonly called ''hopping'' in this instance) as their primary form of locomotion, while others, such as frogs, use it only as a means to escape predators. Jumping is also a key feature of various activities and sports, including the long jump, high jump and show jumping. Physics All jumping involves the application of force against a substrate, which in turn generates a reactive force that propels the jumper away from the substrate. Any solid or liquid capable of producing an opposing force can serve as a substrate, including ground or water. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Novelty Items
Novelty (derived from Latin word ''novus'' for "new") is the quality of being new, or following from that, of being striking, original or unusual. Novelty may be the shared experience of a new cultural phenomenon or the subjective perception of an individual. From the meaning of being unusual usage is derived the concept of the novelty dance (a type of dance that is popular for being unusual or humorous); the novelty song (a musical item that capitalizes on something new, unusual, or a current fad); the novelty show (a competition or display in which exhibits or specimens are in way some novel); and novelty architecture (a building or other structure that is interesting because it has an amusing design). It is also this sense that applies to a novelty item, a small manufactured adornment, toy or collectible. These, in turn are often used as promotional merchandise in marketing. The Glossary of chess#N, chess term, novelty, is used for a move in chess which has never been played bef ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Running Gags
Running is a method of terrestrial locomotion allowing humans and other animals to move rapidly on foot. Running is a type of gait characterized by an aerial phase in which all feet are above the ground (though there are exceptions). This is in contrast to walking, where one foot is always in contact with the ground, the legs are kept mostly straight and the center of gravity vaults over the stance leg or legs in an inverted pendulum fashion.Biewener, A. A. 2003. Animal Locomotion. Oxford University Press, US. books.google.com/ref> A feature of a running body from the viewpoint of spring-mass mechanics is that changes in kinetic and potential energy within a stride occur simultaneously, with energy storage accomplished by springy tendons and passive muscle elasticity. The term running can refer to any of a variety of speeds ranging from jogging to sprinting. Running in humans is associated with improved health and life expectancy. It is assumed that the ancestors of humankin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mighty Beanz
Mighty Beanz is a collectable children's toy line of plastic beans created by Moose Enterprises in Melbourne, Australia. The primary Mighty Beanz game is to race the beanz down different types of battle stages. History Original line The Mighty Beanz line was originally launched in Australia at the beginning of 2002 and found their way to United States markets that summer. Five beans were created: * “Series 1” included 60 beanz (1-60) divided into teams of one, along with a red carrying case. * “Series 2” introduced 70 all new Mighty Beanz (60-130) . Again, these were divided into teams of one with some beans able to glow in the dark. * “Series 3” produced only 60 new Mighty Beanz (131-190). This line of Beanz introduced color changing abilities, along with a new green carrying case. * “Series 4” produced another 60 Mighty Beanz (191-250). This time around, the Beanz were arranged into teams of three and also introduced a new mega Bean, which was substantially ...

Formicarium
A formicarium or ant farm is a vivarium which is designed primarily for the study of ant colonies and how ants behave. Those who study ant behavior are known as myrmecologists. History The formicarium was invented by Charles Janet, a French entomologist and polymath, who had the idea of reducing the three dimensions of an ant nest to the virtual two dimensions between two panes of glass. His design was exhibited in the Exposition Universelle (1900) in Paris. Janet's invention was recognized by his promotion to Chevalier (Knight) of the Legion of Honour, but he did not obtain a patent for, nor attempt to market his creation. The first commercially sold formicarium was introduced around 1929 by Frank Eugene Austin (1873–1964), an inventor and professor at the Thayer School of Engineering at Dartmouth College. Austin received a patent for his formicarium on June 16, 1931, as well as further patents for its continued development. Austin included whimsical painted or wooden sce ...

Sea-Monkeys
Sea-Monkeys is a marketing term for brine shrimp (''Artemia'') sold as novelty aquarium pets. Developed in the United States in 1957 by Harold von Braunhut, they are sold as eggs intended to be added to water, and almost always come bundled in a kit of three pouches and instructions. Sometimes a small tank and additional pouches are included. The product was heavily marketed in the 1960s and 70s, especially in comic books, and remains a presence in popular culture. History Ant farms had been popularized in 1956 by Milton Levine. Harold von Braunhut invented a brine-shrimp-based product the next year, 1957. Von Braunhut collaborated with a marine biologist, Anthony D'Agostino, to develop the proper mix of nutrients and chemicals in dry form that could be added to plain tap water to create a suitable habitat for the shrimp to thrive. Von Braunhut was granted a patent for this process on July 4, 1972. They were initially called "Instant Life" and sold for $0.49, but von Braunhut ...

Emporia Melanobasis
''Emporia melanobasis'' is a species of snout moth in the genus '' Emporia''. It was described by Boris Balinsky in 1991, and is known from South Africa. Jumping beans The larvae pupate inside fruit of ''Spirostachys africana''. Larvae develop with the growing fruits which show no external damage. When the fruits are mature each splits into three cocci. The larvae jack-knife inside the fallen segments, causing them to move about erratically and vigorously, to the surprise of the uninitiated. This has led to the name "jumping bean tree". A similar phenomenon occurs with the Mexican jumping bean, ''Sebastiania'' sp., which also belong to the Euphorbia family. This bean is parasitised by the moth ''Cydia saltitans ''Cydia saltitans'' or jumping bean moth is a moth from Mexico that is most widely known as its larva, where it inhabits the carpels of seeds from several related shrubby trees, mainly '' Sebastiania pavoniana'' or '' Sapium biloculare'' ( syn ...''.

Spirostachys Africana
''Spirostachys africana'' is a medium-sized (about tall) deciduous tree with a straight, clear trunk, occurring in the warmer parts of Southern Africa. Its wood is known as tamboti, tambotie, tambootie or tambuti. It prefers growing in single-species copses in deciduous woodland, often along watercourses or on brackish flats and sandy soils. Description The leaves are small, elliptic with crenate margins, and turn bright red in winter before dropping. The petiole has 2 small glands at the distal end. The grey-black rough bark is distinctively split into neat rectangles. The catkin-like flowers appear in early spring before the leaves. Male and female flowers are borne separately on the same tree (monoecious). The small 3-lobed capsules or schizocarps split into three equal indehiscent segments ( mericarps or cocci) when ripe; on a warm day this splitting ( dehiscence) can sound like a distant fusillade of shots. The seeds are globose with a chartaceous testa. Wood and toxic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
