SWIMMING SPAGHETTI
Spaghetti is denser than water and, therefore, sinks when placed in water. When spaghetti is placed in a solution of baking soda and vinegar, thespaghetti rises to the surface due to the carbon dioxide gas that adheres to it. When the spaghetti reaches the surface, the gas is released, and the spaghetti sinks again.
Whatis the importance of our Swimming Spaghetti experiment?
The movement of the spaghetti is caused by the Carbon Dioxide (CO2) evolved from the reaction of Vinegar (Acetic Acid)and Bicarbonate Soda. It is the evidence of the chemical reaction.
Make spaghetti do tricks with this fun and fizzy experiment.
What You Need:
* cup of uncookedspaghetti
* 1 water
* 2 teaspoons of baking soda
* 5 teaspoons of vinegar
* tall clear glass
What You Do:
Put water and baking soda in the glass. Stir untilthe baking soda is dissolved. Break spaghetti into 1-inch pieces. Put about 6 pieces in the glass. They will sink to the bottom. Add vinegar to the mixture in the glass.Observe what happens to the pieces of spaghetti. Add more vinegar as the action starts to slow down.
What’s Going On:
When baking soda and vinegar are mixed together, achemical reaction occurs. It produces a gas called carbon dioxide, which forms lots of bubbles on top of the mixture and smaller bubbles at the bottom of the glass. These littlebubbles stick to the spaghetti and make it float to the surface, just as you do when you sit on a swimming pool noodle! When the spaghetti reaches the surface, the bubbles popand the spaghetti sinks to the bottom.
hope you liked this experiment
