your computer key board has more germs than your toilet.
There are more germs under a fingernail than on a toilet seat!

The reason the pennies sink in water is because of an idea called density. The pennies have more density than the water, and so the pennies sink. Anything with more density than water will sink in water, but other objects that have less density than water will float.
Depending where it is leaking, a toilet may need to be replaced entirely. If it is more than twenty years old, that may be a wise precaution. Leaking from the bottom may mean that you need to remove the toilet, replace the wax ring and bolt it back down. For a sink, it is all about the piping and fixtures, in most cases. I have had a cast iron sink leak, though.
Yes, dinghys sink. Some are more likely to than others.
a lot, i would recommend you to use a toilet tissue or something else other than that
Not all heavy things sink. Things that are more dense than the liquid around them will sink.
the objects whose density is more than that of fluid sink in the liquid
