Techniques used to map functioning areas of the brain are discussed. Larger groups will be divided and the demo will be conducted twice. This demonstration provides an uplifting moment. Ceramic superconductors are used to demonstrate the Meissner effect, the levitation of a magnet and the critical temperature of two different superconductors is determined. Research into superconductors at LANL is discussed.
Liquid nitrogen is used to perform the experiments.
This demonstration can be combined with the cryogenics one. This demonstration first uses a thermoacoustic engine to convert heat into audible sound waves. Then a thermoacoutic refrigerator uses sound waves to cool down the air around it. LANL scientists, in conjunction with industry, have used the combination of these two processes to turn hot into cold.
