“Calcium gluconate snake” experiment
How to make snakes from a handful of calcium gluconate tablets
Snakes grow out of tablets of calcium gluconate!
Avoid burns! Wear protective glasses and gloves. Don’t conduct the experiment near inflammable substances and objects. The experiment must be carried out in a well-ventilated room. Observe general safety recommendations.
Reagents and equipment:
- several tablets of calcium gluconate;
- solid fuel;
Calcium gluconate breaks down when heated. Calcium oxide, carbon, water vapor and carbon dioxide form. Water vapor and carbon dioxide froth the carbon and calcium oxide, turning them into enormous gray “snakes”:
