A sparkler is a type of hand-held firework that burns slowly while emitting colored flames, sparks, and other effects. The "classic" type of sparkler consists of a stiff metal wire approximately 20 cm (8 inches) long that has been dipped in a thick batter of slow-burning pyrotechnic composition and allowed to dry. The composition contains these components, one or more of each category.

Albert Einstein, 14 March 1879–18 April 1955) was a theoretical physicist, philosopher and author who is widely regarded as one of the most influential and best known scientists and intellectuals of all time. He is often regarded as the father of modern physics. He received the 1921 Nobel Prize in Physics "for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect." His many contributions to physics include the special and general theories of relativity, the founding of relativistic cosmology, the first post-Newtonian expansion, explaining the perihelion advance of Mercury, prediction of the deflection of light by gravity and gravitational lensing, the first fluctuation dissipation theorem which explained the Brownian movement of molecules, the photon theory and wave-particle duality, the quantum theory of atomic motion in solids, the zero-point energy concept, the semiclassical version of the Schrödinger equation, and the quantum theory of a monatomic gas which predicted Bose–Einstein condensation. Einstein published more than 300 scientific and over 150 non-scientific works; he additionally wrote and commentated prolifically on various philosophical and political subjects. His great intelligence and originality has made the word "Einstein" synonymous with genius.

Albert Einstein fled Nazi Germany for good, moving to the United States. He later became an American citizen and he remained in the United States for the rest of his life. Einstein had won the Nobel Prize in Physics in 1921 and was respected the world over. In January 1933, Adolf Hitler became Chancellor of Germany and very quickly legalized professional discrimination and persecution of Jews. Einstein, realizing the danger, left Germany forever. Prominent German physicists, led by Einstein's fellow Nobel Prize winners Philipp Lenard and Johannes Stark, initiated the Deutsche Physik (German physics) movement to discredit Einstein's work as Judische Physik (Jewish Physics).Albert Einstein, 14 March 1879–18 April 1955) was a theoretical physicist, philosopher and author who is widely regarded as one of the most influential and best known scientists and intellectuals of all time.
