I have a science fair and I need a little help pls :)

Well, actually I was workin on my science fair project which is Orange Juice vs. Sports drink (u can see details about the project on www.sciencebuddies.com). Well the project is actually about which has more electrolytes to replace the ones u lose during exercises? Soo I brought everything even the hypothesis and I made the experiment and Idk if the problem is in the multimeter or what cuz everytime I try the multimeter doesnt read anything...and what is the sports drink? What is it composed of? And where can I find it? Any ideas??

A multimeter will read AC voltage, DC Voltage and Resistance in Ohms. Some, but not, all read amperage. You will need one with that ability to measure conductance; the current that flows through the liquid divided by the voltage you applied to it. Do the same test on each liquid and compare the results.

"Sports drinks" are drinks like the brand name, "GatorAid," that are promoted to replace electrolytes, such as sodium and potassium, that you lose in sweat during strenuous exercise. Chloride, calcium, and phosphate ions are also electrolytes.

You will need the instructions on this link:
