Eye Popper
An eye popper, rubber popper, hopper popper or jumping popper is a children's toy. It consists of a small, dome-shaped piece of rubber or similar material resembling a half of a rubber ball; the shape of a smile is often imprinted on the dome. When pressed, the object inverts and becomes unstable and, after a few seconds, undergoes snap-through buckling to pop back into its original shape, making a loud popping sound. If resting on the ground when this happens, the toy will fly several feet into the air. It can also be thrown on the ground, causing it to pop upward. The eye popper's behavior resembles the process by which a ball compresses upon hitting a hard surface.

Jumping Toy Patent US2153957
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] |

Dome
A dome () is an architectural element similar to the hollow upper half of a sphere. There is significant overlap with the term cupola, which may also refer to a dome or a structure on top of a dome. The precise definition of a dome has been a matter of controversy and there are a wide variety of forms and specialized terms to describe them. A dome can rest directly upon a Rotunda (architecture), rotunda wall, a Tholobate, drum, or a system of squinches or pendentives used to accommodate the transition in shape from a rectangular or square space to the round or polygonal base of the dome. The dome's apex may be closed or may be open in the form of an Oculus (architecture), oculus, which may itself be covered with a roof lantern and cupola. Domes have a long architectural lineage that extends back into prehistory. Domes were built in ancient Mesopotamia, and they have been found in Persian architecture, Persian, Ancient Greek architecture, Hellenistic, Ancient Roman architecture, ...

Rubber
Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Thailand, Malaysia, and Indonesia are three of the leading rubber producers. Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the rubber tree (''Hevea brasiliensis'') or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". The latex then is refined into the rubber that is ready for commercial processing. In major areas, latex is allowed to coagulate in the collection cup. The coagulated lumps are collected and processed into dry forms for sale. Natural rubber is used extensively in many applications and products, either alone or in combination wit ...

Deflection (physics)
In physics, deflection is a change in a moving object's velocity, hence its trajectory, as a consequence of contact (collision) with a surface or the influence of a non-contact force field. Examples of the former include a ball bouncing off the ground or a bat; examples of the latter include a beam of electrons used to produce a picture, or the relativistic bending of light due to gravity. Deflective efficiency An object's deflective efficiency can never equal or surpass 100%, for example: *a mirror will never reflect exactly the same amount of light cast upon it, though it may concentrate the light which is reflected into a narrower beam. *on hitting the ground, a ball previously in free-fall (meaning no force other than gravity acted upon it) will never bounce back up to the place where it first started to descend. This transfer of some energy into heat or other radiation is a consequence of the theory of thermodynamics, where, for every such interaction, some energy mus ...

Pop It (toy)
A Pop-It (also known as Go Pop and Last One Lost) is a fidget toy consisting of a usually-brightly colored silicone tray with pokable bubbles, similar to bubble wrap, that can be flipped and re-used. They come in a variety of colors, shapes, and sizes, and even come in wearable formats. It is marketed as a stress-reliever and rose in popularity in the spring of 2021 due to TikTok influencers as well as boredom and stress attributed to the COVID-19 pandemic. Origin The mechanical design of the Pop-It bubble popper was originally invented in 1975 by Theo and Ora Coster of Theora Concepts: a married Israeli couple who had invented many games including ''Guess Who?'' and ''Zingo!''.Cramer, Philissa (September 13, 2021)"Anne Frank’s Israeli classmate behind popular breast-inspired fidget toy" ''The Times of Israel'' Retrieved September 15, 2021 Incidentally, Theo was a former classmate of Anne Frank.

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.
