Grace and I did a fun little experiment yesterday that demonstrated the fluid properties of gases.
First we gathered up our materials: candle, lighter, measuring cup, vinegar, baking soda, spoon, and a piece of thick paper (cut to 12″ by 4″ and folded in half lengthwise).
We lit the candle and let it be all peaceful and glowy while we went to the next step.
We measured 1/4 cup vinegar into our measuring cup. Then we added a tablespoon of baking soda and enjoyed the show.
When the bubbling calmed a bit, we used the paper as a trough and “poured” the gas from the measuring cup. (If you’re doing this at home, make sure you don’t put the paper in the flame. Also, don’t pour any of the liquid on the flame…just tilt the measuring cup enough to let the gas on top “pour” out.)
And what do you think happened? Check back for the Week in Pictures this weekend, and I’ll let you know how our experiment turned out. 😉
