One OLDER style of extinguisher was filled with water and bicarbonate of soda (baking soda)- AND had a small bottle of an acid. When it was turned upside down, the acid ran out of the bottle, mixed with the soda, and produced carbon dioxide gas. The gas forced the water out under pressure. NOT USED ON MOST MODERN EXTINGUISHERS.

Your question wasn't really clear but I'm assuming you mean how do you test a dry chemical fire extinguisher at home. Normally these types of extinguishers are tested at home by simply turning them upside down and listening to them to make sure the dry powder hasn't started to cake in the bottom. If you hear the sound and the gauge on the top of the bottle shows in the "green" the extinguisher is fine. Don't try to test them by pulling the trigger and seeing if they shoot, there's not a heck of a lot of powder in there to play around with.

Can you be more specific as to who does this?If you mean glasses already on the table when you are seated in restaurants, having them upside down keeps dust from falling into the glass and allows them to drain if they weren't QUITE dry when placed there.
