From a broken thermometer stems liquid mercury, which has the property to evaporate at room temperature. And mercury vapor are the strongest poison. Mercury from a broken thermometer when the strike is broken into small droplets and scattered throughout the room. It easily penetrates into the cracks of the floors, in the gap under the skirting boards, stuck in the pile of carpets. Gradually evaporating, it poisons the air. If the person is breathing this air, mercury accumulates in the body - the kidneys, liver, the brain and the person develops chronic mercury intoxication.

First, during operation of the vacuum cleaner is heated, and thereby enhances the evaporation of mercury.
Secondly, the air passes through the motor of the vacuum cleaner, and engine parts made of nonferrous metals, mercury is formed, the film - amalgam. This vacuum cleaner becomes a distributor of mercury vapor, including in a landfill.
Thirdly, from the back exit of the vacuum cleaner microcephaly mercury disperse air throughout the apartment.
No need to roll mercury balls on the floor or collect them in one drop! Not pegmatite mercury twigs: twigs will only crushed the poisonous bulbs in small mercury dust.
Mercury is best to collect the most conventional syringe. You can use paper towels soaked sunflower oil, water-soaked newspaper drops of mercury will stick to them.
