Bottle Rocket

In room one for the last three weeks, we have been doing science fair. My group decided to do a bottle rocket. The first thing we did was plan who was buying what. After school it was time to buy what was on our lists. Then we were starting to build it. After we finished building, it was time to test with the vinegar and baking soda. We poured the ingredients in the bottle. The first 2 times it did not work because we had the wrong amount of vinegar and baking soda, but the third time it worked. It was really fun doing science.
