i need to finish a science experiment and i have to do different ph's on it so how do you make acid water with ingredients you can find in a regular house?

Soda water is carbonic acid (CO2 disolved in water)
Vinegar is acidic (acetic acid)
Lemon juice (citric acid)
You can use these straight or diluted with water to change the concentration

I am into electronics/robotics so I'll tell you to build a small robot. There are some very simple. - Line follower robot : You put a line of duct tape on the floor and the robot follows it. You can find explanations and how to do it anywhere (google, yahoo or bing) - Obstacle avoidance: Like its name indicates, the robots moves into a space and avoid obstacles on its way. - A system to turn on the light automatically as it gets darker. Use of a Light Dependent Resistor (LDR) to turn on a LED.
