How to Test If Alcohol Has Methanol
Instructions
1.
Place two 1 oz. samples of the alcohol in question into separate containers.
2.
Mix 5 grams of potassium dichromate with one of the samples and let it sit for 10 to 15 minutes.
3.
Waft the alcohol and potassium dichromate sample toward your nose. If you detect an acrid smell, methanol is present in the alcohol.
4
Place a piece of red litmus paper in the second sample and wait 1 to 2 minutes.
5
Check the litmus paper. If it has turned from red to blue, methanol is present.
6
Dispose of the alcohol properly and do not consume it as it is highly poisonous.

Could be interesting taking these items on your trip to Bali or where-ever and conducting your own science laboratory at the local Bars. Imagine 100's or 1,000's or tens of thousands of Aussies conducting Methanol testing science labs throughout the bars in Bali every day & every night. Litmus paper everywhere.
