1 Wear safety goggles to protect your eyes. 2  Never use a plunger if a chemical cleaner is present in the drain; you risk splashing the chemical on yourself.  Never remove a trap with chemicals present; you risk burns to your skin. Call a professional but make certain you inform them of what chemical you used.
Originally Answered: Why is the Moon drifting away by 1 cm each year? Because of tidal forces between moon and Earth. As Earth and moon pull each other, bulges are created on the surface.
The effect of the Moon inching away from Earth is barely noticeable on human timescales. But millions of years from now, the effects will be more tangible. The tides will be weaker because of the Moon's weaker gravitational pull. The release of tidal energy in Earth's oceans and crust will continue to slow our own planet's spin and thus increase the length of our day (it is increasing at a rate of one second every 50,000 years).
