I think that the reaction between the baking soda and vinegar is caused by the reaction between the carbon in vinegar and the sodium in baking soda.


I observed that the CO2 stayed in the cup when they poured in on the candle. I also observed that the excess baking soda/vinegar solution stayed on the bottom of the cup.

Why did the carbon dioxide stay in the cup when cooper poured it in? What is the melting point of pure sodium?


things I didn't know:
-80% of the air is nitrogen
-pure sodium explodes in water
-rubidium explodes in water
-potassium explodes in water
-electrons "don't exist"
-anything with only one electron reacts with water

Myth busters, january 14, 2012.

The myth we watched today was if CDs would shatter if they spun too fast. The myth was busted because CDs are strong enough to resist household CD drives and would have to go over fifty thousand rpm to shatter. I think that I would have tested the phone-gas station explosion myth with more variables. I think that they should test if you can melt anything.
