A scientific demonstration is a procedure carried out for the purposes of demonstrating scientific principles, rather than for hypothesis testing or knowledge gathering (although they may originally have been carried out for these purposes). Most scientific demonstrations are simple laboratory demonstrations intended to demonstrate physical ...
Chemical garden. Diet Coke and Mentos eruption — demonstrates bubble nucleation. Dry ice color show. Elephant toothpaste. Fizz keeper. Flame test. Magic sand — demonstrates hydrophobic substances. Mercury beating heart — demonstrates electrochemical redox reaction. and an effect of a non-homogeneous electrical double layer.
The International Space Station is a platform for scientific research that requires one or more of the unusual conditions present in low Earth orbit (for example microgravity, (cosmic) - radiation and extreme temperatures). The primary fields of research include human research, space medicine, life sciences, physical sciences, astronomy and ...
Franklin bells (also known as lightning bells) are an early demonstration of electric charge designed to work with a Leyden jar or a lightning rod. Franklin bells are only a qualitative indicator of electric charge and were used for simple demonstrations rather than research. The bells are an adaptation to the first device that converted ...
Jeffrey Vinokur was born in 1990 to Russian immigrant parents. He attended Montvale Public Schools. [18] His early interest in science was fueled by doing kitchen science experiments in elementary school, which later progressed to creating a chemistry lab in his parents' garage at age 14, where he would do amateur experiments like making sodium metal from household supplies.

In 1663 (or, according to some sources, in 1661) the same demonstration was given in Berlin before Frederick William, Elector of Brandenburg with twenty-four horses. The experiment became a popular way to illustrate the principles of air pressure, and many smaller copies of the hemispheres were made, and are used to this day in science classes ...
