- 1). Light the candle. Let some wax drip onto the spoon. Extinguish the candle, then press the bottom of the candle into the melted wax to attach the candle to the spoon.
- 2). Relight the candle. Hold it by the spoon handle and dip it into each of the two beakers. The candle will stay lit, demonstrating that the beakers are filled with oxygen.
- 3). In one of the beakers, mix two tsp. of baking soda with one cup of vinegar. The solution will bubble, generating carbon dioxide.
- 4). Lower the candle into the empty beaker to show that the beaker is still filled with air. Lower it into the other beaker.The candle will go out, demonstrating that there is carbon dioxide in this beaker.
- 5). Pick up the beaker containing carbon dioxide and hold it over the other beaker as if you were pouring a liquid. Make a comment or two such as, "Uh oh, I think I spilled some."
- 6). Relight the candle. Lower it into the beaker you just poured from. It will stay lit. Lower it into the other beaker. It will go out, proving that you have transferred the carbon dioxide.
