A doll is a model typically of a human or humanoid character, often used as a toy for children. Dolls have also been used in traditional religious rituals throughout the world. Traditional dolls made of materials such as clay and wood are found in the Americas, Asia, Africa and Europe. The earliest documented dolls go back to the ancient civilizations of Egypt, Greece, and Rome. They have been made as crude, rudimentary playthings as well as elaborate art. Modern doll manufacturing has its roots in Germany, from the 15th century. With industrialization and new materials such as porcelain and plastic, dolls were increasingly mass-produced. During the 20th century, dolls became increasingly popular as collectibles.

Fashion is a term used interchangeably to describe the creation of clothing, footwear, accessories, cosmetics, and jewellery of different cultural aesthetics and their mix and match into outfits that depict distinctive ways of dressing (styles and trends) as signifiers of social status, self-expression, and group belonging. As a multifaceted term, fashion describes an industry, styles, aesthetics, and trends.

The term 'fashion' originates from the Latin word 'Facere,' which means 'to make,' and describes the manufacturing, mixing, and wearing of outfits adorned with specific cultural aesthetics, patterns, motifs, shapes, and cuts, allowing people to showcase their group belonging, values, meanings, beliefs, and ways of life. Given the rise in mass production of commodities and clothing at lower prices and global reach, reducing fashion's environmental impact and improving sustainability has become an urgent issue among politicians, brands, and consumers.

Playsets, or play sets, are themed collections of similar toys designed to work together to enact some action or event. The most common toy playsets involve plastic figures, accessories, and possibly buildings or scenery, purchased together in a common box. Some sets during the 1960s and 1970s were offered within metal "suitcase" containers that also functioned as part of the playset.

First pioneered by metal figure manufacturers around the turn of the 20th century, usually as military "play" figures with simple accessories, the concept of the playset was further developed by companies like Marx Toys, Superior Toy, Remco, Deluxe Reading, Multiple Toymakers (MPC) and others throughout the Baby Boomer era. Several manufacturers continue to produce playsets today.

A rainbow is an optical phenomenon caused by refraction, internal reflection and dispersion of light in water droplets resulting in a continuous spectrum of light appearing in the sky. The rainbow takes the form of a multicoloured circular arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the Sun. Rainbows can be caused by many forms of airborne water. These include not only rain, but also mist, spray, and airborne dew.

Rainbows can be full circles. However, the observer normally sees only an arc formed by illuminated droplets above the ground, and centered on a line from the Sun to the observer's eye.

In a primary rainbow, the arc shows red on the outer part and violet on the inner side. This rainbow is caused by light being refracted when entering a droplet of water, then reflected inside on the back of the droplet and refracted again when leaving it.

In a double rainbow, a second arc is seen outside the primary arc, and has the order of its colours reversed, with red on the inner side of the arc. This is caused by the light being reflected twice on the inside of the droplet before leaving it.
