With fellow medac students decided to check the degree in the drink of spirits from the Department of Chemistry of alcohol and water. At the department of honey physics, a spirometer was applied. Mix 2/3 and 1/3 of water. I put a spirometer in the bank. He is not drowning! Add water to 50% - it won't drown again. We checked what we diluted. We understood that we were doing everything right and went to the basement. It turned out even before our arrival he crushed from the alcoholometer on the cargo for the sperm and the alcoholometer burned in order not to write!
