Other than the bad breath experiment, and another in which two seniors made Jell-O (that was the whole experiment: They concluded that they could indeed make delicious Jell-O), and one more in which a third grader accidentally misspelled a section title "Resluts," the saddest experiment I've seen at a science fair actually says a lot about the problems with modern science.
For this purpose we applied computerized single-breath experiments to 11 anesthetized paralyzed rabbits (weight 2.8 3.8 kg) at various alveolar volumes (45 72 ml) by studying the almost entire inspiratory limb of the respective pressure/volume curves (intrapulmonary pressure: 6 27 cmH2O).
This breath-holding experiment, conducted last week at a swimming pool on Grand Cayman Island, was being run by Ralph Potkin, a pulmonologist in Los Angeles who is a researcher trying to understand the human propensity for going without air.
Whales and dolphins would be at the top of his list, but he isn't holding his breath for those experiments to be published.
As the decades pass, city symphonies only increase in interest, rising above their initial existence as breath-taking avant garde experiments to the level of vitally important cultural documents.
Among the devices in his home: a Zeo headband (to monitor brain waves and sleep cycles), a pulse oximeter (to check the oxygen saturation of his blood), a glucometer (to track blood sugar) and a kitchen timer (for many experiments, including breath-holding, which he can do for more than three minutes thanks to tutelage from the illusionist David Blaine).
At each phase of this experiment, after breath sounds were recorded, a broad-band sound signal was introduced into the airway during a 10-s respiratory hold for measurement of transfer function magnitude and phase and coherence of the external signal.
Featured at the Fire & Fright Festival and commissioned by onedotzero, Atmeture is an "experiment in breath and space," describe Loop.pH founders Mathias Gmachl and Rachel Wingfield.
Animals were allowed to breath spontaneously during the experiment and were placed in a heated cradle to maintain the core body temperature at approx. 37°C.
Animals were allowed to breath normally throughout the experiment except for the during the one hour of aerosolisation.
If you still cannot see your breath, try exhaling slower/faster, experimenting with different mouth shapes, and/or making the part beyond the edge of the cup bigger/smaller.
