A piñata is a cardboard and papier-mâché container covered with brightly-coloured tissue paper and containing sweets or small gifts. A piñata is supposed to be broken, often in a game involving blindfolded players hitting a suspended piñata. The piñata probably originates from Mexico, among the Aztecs, Mayans and other native peoples who broke filled pots because the spilling of contents signified abudance or favours from the gods. Some people believed the Spanish conquistadors brought the piñata to Mexico, where it gained in popularity because of their traditions of breaking clay pots.
The Doppler effect is the change in frequency of a wave for an obsever moving relative to the source of the wave. The effect is often associated with an observer hearing a vehicle's horn approaching, passing and receding. The received frequency is higher than the emitted frequency during the approach, the same at the moment it passes and lower as it recedes. The Doppler effect is named after Austrian physicist Christian Doppler (1803 - 1853).
Blaine Greenhalgh from Brigham Young University explains the Doppler effect.

A Ouija board (pronounced 'wee-ja' or 'wee-gee') is a board usually marked with the alphabet, numbers 0-9, 'yes', 'no' and 'goodbye'. Some people believe the Ouija board can be used to communicate with the spirit world through a planchette (small wooden piece) held by a person on the board, which then supposedly moves as a spirit relays a message. Talking boards have been traced back to ancient China, Greece and Rome. The Ouija board was first sold in the late 1890s as a parlour game before American Spiritualist Pearl Curran popularised it as an instrument to contact spirits during World War I. Many scientists believe Ouija boards can be explained by the ideo-motor response - the theory that a mental image can cause a reflexive or muscular reaction that the subject may not be conscious of.
Milton Bradley (1836 - 1911) is often considered to be the pioneer of the board game industry in the United States. He ran the Milton Bradley Company, now a subsidiary of Hasbro, and first released a board game, The Checkered Game of Life, in 1960. This game involved players spinning a teetotum (gambling spinningtp) to advance to corresponding squares, which represented social virtues or vices. The winner was whoever was first to accumulate one hundred points. Bradley's game was the first to define success in terms of personal virtues as a means to an end rather than end in themselves, reflecting the growing importance of personal wealth after the Civil War.
