I've never tried the gummi worm procedure that Steve shows off at the beginning, but I really want to. Wonder if sodium alginate is available in a glowy solution like he uses...probably from his website.
The formation of the 'worms' is curious. In looking Gaviscon up at Wikipedia, here's what I found...
The formulation of Gaviscon varies by manufacturer. The three active ingredients in Reckitt Benckiser's version are sodium alginate, a bicarbonate (either sodium or potassium in variants) and an antacid (calcium carbonate). The GlaxoSmithKline variant lists only antacids as its active ingredients (aluminum hydroxide and either magnesium carbonate or magnesium trisilicate). Alginic acid and sodium bicarbonate are listed as inactive ingredients. The combination of alginic acid and a bicarbonate forms a layer on the contents of the stomach, which prevents stomach acid from refluxing up into the esophagus. If reflux does occur the protective barrier is the first to contact the esophageal mucosa, instead of gastric contents.What will science think of next?
