- Liquid oxygen will be made on site, using liquid nitrogen, also dry ice, using bottled gas. - Liquid nitrogen is used to show some dramatic changes of matter at low temperatures, producing fog, balloon shrinking, as a fire extinguisher, for making ice-cream, some compounds show superconductivity, etc. - Liquid oxygen as a fire promoter. - Carbon dioxide as a dry ice, producing fog, sublimes, effect of dissolving in water. - Helium and dinitrogen oxide gases when inhaled change the person's voice. - Hydrogen explodes with air (clean fuel in future), hydrogen bubbles move up, but also burn without explosion. ---------------------------------------------------------- El nitrógeno líquido se usa para mostrar espectaculares cambios en de la materia a bajas temperaturas. Se muestra el oxígeno como activador del fuego y el dióxido de carbono como hielo seco. Cómo el helio y el dióxido de nitrógeno provocan el cambio de voz y el hidrógeno como energía limpia.

The experiments from chemistry and physics that are many times not part of the primary and secondary school curricula will be presented in very attractive way and will require the participation of viewers. ---------------------------------------------------------------------------------- Los experimentos de química y física que, con frecuencia, no forman parte del currículum de Primaria o Secundaria, se presentan de manera muy atractiva con la participación activa del público.
