In addition to the Canadian unit of Previews there are seven units operating 'n vari- ous parts of the United States, and 14 units are in use through- out the rest of the world. Dur- ing the past 11 years, more than 18 million children and adults have seen this presenta- tion. The theme of the show is that today's material progress is the result of work by scientists and engineers, and that many oppor- tunities await the student in the exciting fields of science and engineering. By using original: demonstra- tions in the fascinating field of popular science to develop this theme, it is felt that young people are entertained, enlight- ened, and inspired. The sequence of experiments is as follows: Polymer Chemistry. A_ rela- tively new and exciting field of chemistry which holds great promise for the future. It is demonstrated by three 2xperi- ments: in just 60 seconds, syn- thetic rubber literally jumps out of the pop bottle in which it is manufactured; a raw egg is bounced off a _ polyurethane foam plastic cake, made right on stage in just two minutes; and two metal discs are miracu- lously held together by a single drop of a new, miracle ad- hesive, after only 35 seconds. Ground Effect Machine, Dem- onstrates that in the' vehicle of tomorrow, a cushion of air may replace wheels. Sunmobile. A model car that illustrates one possible method of using sunshine as a power source. This model actually runs on sunhine. 1 Fuel Cell. A method for ¢on- verting the chemical energy of fuel directly into electrical ener- gy without the usual _ inter- mediate steps of fire, steam, * turbine jand generator. Suitcase with a mind of its own. A -"'misbehaving" suit- case illustrates scientific princi- ples essential to space travel. Exploding Wire. A small piece of equipment. shows that stor- ing energy over a relatively "long period, and discharging it instantly, may enable us. to obtain enprmous 'peak power outputs. , Jet propulsion.
