The water hyacinth has a large surface area that lays over the top of the water, which distributes its weight and increases its buoyancy sufficient to keep it floating.
Because that piece of charcoal is lighter that the water, so it floats.
Soil floats on water!
The weight of the substances are largely immaterial. What matters is the density. Assuming fresh water to have a density of 1.0 anything with a lighter density will float in it. For example, oil generally has a density of about 0.8, so it floats in water. Concrete has a density of about 2.4, so it sinks. http://physics.about.com/od/fluidmechanics/a/commondens.htm
Oh, dude, an apple floats higher in water than a pepper because apples have a lower density than peppers. It's like apples are the cool kids at the pool party, just chilling on the surface while the peppers sink to the bottom. So, if you ever need to impress someone with your knowledge of floating produce, now you know!
Yes, the water hyacinth, Eichhornia crassipes, floats.
The water hyacinth float on the surface, and are not attached to the bottom.

there is an expanded leaf stalk that has an air inside and serves as a float -lawrence 11 y/o
could be water hyacinth Yes, water Hyacinth's do float on the water surface. Hyacinths have leaves that look like hippo ears. Water lilies also float on the water surface. They have flat leaves that fill the water surface and the flowers poke up among the leaves. Patti Rose www.rosepond.com

Cork floats in water because it is less dense than water. Its buoyant property allows it to stay afloat on the water's surface.
It floats or connects to rocks by the surface.
Fat floats on water, but not on the surface of the troposphere.
