584. How would you suggest changing the proposedexperiment to assure a more likely successful outcome?Likewise, what might have been eliminated to assuresuccessful results?5. What about the filming of the demonstration? Would ithave been easier on Challenger or on earth using the videocamera and tripod.
59THE <strong>LOST</strong> EFF<strong>ER</strong>VESCENCE LESSONThe Mystery of Christa’s Big Bubble“See the bubbles…the big one…I love it.”Background Science Summary:Effervescence, i.e., the presence of bubbles in a liquid, can beproduced both by a chemical reaction and physical phenomena. Thechemical compound contained in an Alka-Selzer® tablet produceseffervescence through a chemical reaction. The tablet with itschemical formula, NaHCO 3, is also known as “baking soda” orsodium bicarbonate. When dissolved in water, the chemical reactionoccurs. It results in the tablet producing, as a byproduct, a gasknown as carbon dioxide with the symbol, CO 2 .Of course, effervescence can be produced in water by simplyblowing carbon dioxide gas into the liquid, pressurizing it. Nochemical reaction is involved. However, the pressure of the gaswithin can be affected through physical means (shaking).
