A tin foil raft, which is just a flat piece of tin foil (which we know is really aluminum foil), floats by means of the surface tension of the water that supports it. We all know that aluminum is more dense than water. A block or other chunk of aluminum would sink in water. But because the aluminum foil is thin, its mass is "spread out" over a wide area, and this causes a broad interaction with the surface tension characteristic of water.

Does mass alone determine wheter an object will float or sink?
No. The key to whether an object floats or sinks is the average density, i.e., mass divided by volume. Also, whether an object will float or not also strictly depends on the surface volume. A piece of tin foil shaped into a boat will float and the same mass of tin foil shaped into a crumpled up ball will not float.

Why does a van der Graff generator repel a stack of tin foil plates?
Since tin foil is a conductor, it acquires the same charge as the van der Graff generator. Likes repel, thus the plates are repelled.

How does an inflatable raft float?
The surface area of the raft displaces the water forcefully which causes float
What is the reason that a crushed tin ball of foil will sink and and flat piece of it floats?
A flat piece of tin foil may float on top of water due to surface tension. A crushed ball of foil does not have near the amount of surface area in contact with the surface of the water, so the surface tension is not sufficient to keep it suspended. Note that if you place a flat sheet of foil in the bottom of a container and pour water in on top of it however, it will not rise to the top to float; you have to place it on top carefully in order to get it to float.
