1. Pop Rocket Challenge

2. Background:
Alka-Seltzer contains citric acid and sodium bicarbonate(baking soda), as well as medicines, stuff for colds, allergies, or whatever else. In a seltzer tablet, Carbon Dioxide (CO2), a gas, is produced as a result of a chemical reaction that is able to start once the acid (citric acid) and base (sodium bicarbonate) are allowed to mix in the water. As the Carbon dioxide (CO2) gas builds up it creates enough pressure to pop the canister off its top thrusting it into the air like a rocket.

4. The Scientific Method

5. The Goal
Your mission is design an experiment that helps answer the following question?
What are the conditions to achieve maximum thrust in a film canister rocket?

6. Parameters.
You are only allowed to use alka-seltzer and water as the materials for your rocket fuel!
You must only test one variable(condition) at a time.
You should test four data points. A data point is the point you test data at, each data point should have a unique set of conditions.
You must have a minimum of three launches for each data point you test. Why is this necessary?
All measurements must be precise, accurate, and in metric units.
