Pure ethanol is a colourless flammable liquid.
The same amount of alcohol may have different effects upon different people. Alcohol is a depressant drug. In small amounts alcohol may produce feelings of relaxation, fun and laughter. It can make it easier for people to enjoy the company of others, and for a short time it may help people forget about things that are worrying them. However, in larger amounts alcohol may cause some people to become aggressive and argumentative.
