Conservation of Mass Investigation

Our experiment involves vinegar (hmmm?), baking soda (ah), balloons (back to hmmm?), soda (tasty), and Pop Rocks (YUM!). Interesting, I'd say so.

Your missions, should you choose to accept it, is this: place Pop Rocks in soda and baking soda in vinegar and find out which produces more gases. Also, James Bond, you must discover whether or not Pop Rocks and soda is a chemical reaction.

Ok, well, we fail as James Bond. -_-' Our test started with the Pop Rocks and Soda. We were supposed to fill a balloon with Pop Rocks then seal the balloon over the soda and pour in the Pop Rocks. However, we failed and broke the balloon so there was a tear in it when we tried to place it over the soda bottle lip. We called in back-up (Mrs. Leland) to help take it off, and the whole lip of the balloon tore off. Dang. So, we improvised by placing the rest of balloon over the bottle. The drawback: the balloon won't fill up to a size bigger than a peanut (a tad exaggeration right there, but it was fairly small: walnut size, maybe). If we squeezed the bottle, the rest of the gas that was in the bottle would be pushed into the balloon. But that's sorta illusional victory, it's like getting a ton of money from Monopoly: you have a million dollars, but you can't buy anything but tiny, plastic houses. You can't even buy a house on boardwalk!

The baking soda and vinegar were a bit more successful. One, our balloon lip didn't break. Two, we didn't have to content our selves with chimera. And three, our balloon was bigger than anything in the nut family. The cliche baking soda and vinegar reacted as was expected with a FWOOSH! The balloon was the size about the size of the snow-globe on Mrs. Leland's desk. About four to six inch diameter. However, when we removed the balloon, we found that not all of the baking soda had gone into the empty bottle and had in fact stuck to the rim of the inside of the bottle (it still had a bit of water in it). I don't think it would've affected our experiment greatly because we used 1 teaspoon of baking soda while a lot of other groups used 1/2 because the top said 1 teaspoon while the bottom said 1/2. }:) Aren't we lucky?

Good job, Bond. You came back . . . alive. What did you find? We found that vinegar and baking soda yielded more of a reaction by observing those on the same mission. Also, I have concluded that Pop Rocks and Soda are not chemical reactions. My fellow assassins . . . I mean assistants . . . betrayed me and said it was a chemical reaction. However, truth prevailed and I, of course, was proved correct. The Pop Rocks were only releasing the carbon dioxide already in the soda as well as the soda dissolved the Pop Rocks therefore releasing the carbon dioxide trapped within the candy. And should you worry that the dissolving is a chemical reaction, it is not; the dissolving of the candy is a physical reaction. Mission complete.
