A significant fraction of gifts are unwanted, or the giver pays more for the item than the recipient values it, resulting in a misallocation of economic resources known as a deadweight loss. Unwanted gifts are often regifted, donated to charity, or thrown away. A gift that actually imposes a burden on the recipient, either due to maintenance or storage or disposal costs, is known as a white elephant.
During the Second World War, some new types of toys were created through accidental innovation. After trying to create a replacement for synthetic rubber, the American Earl L. Warrick inadvertently invented "nutty putty" during World War II. Later, Peter Hodgson recognized the potential as a childhood plaything and packaged it as Silly Putty. Similarly, Play-Doh was originally created as a wallpaper cleaner. In 1943 Richard James was experimenting with springs as part of his military research when he saw one come loose and fall to the floor. He was intrigued by the way it flopped around on the floor. He spent two years fine-tuning the design to find the best gauge of steel and coil; the result was the Slinky, which went on to sell in stores throughout the United States.
Pretend play is an essential part of a well-rounded childhood, helping kids develop intellectually, physically, socially and emotionally. By the age of three, your children will naturally begin to engage in pretend play, and you can ensure this activity is safe and rewarding by providing them with a good selection of age-appropriate toys. Make-believe must-haves include toy kitchens and play workshops, costumes, musical instruments and active toys like blasters and water guns. As your kids spend more time and energy in pretend worlds, their understanding of the real world will grow, and the skills they acquire will benefit them for a lifetime.
