A needle is fully metal whereas a ship is hollow so it floats
No. Fimo sinks.
It sinks, it's too dense to float.
Because the pin is more dense than the water. Density and weight aren't the same thing. A feather, for example, has less density than the water so it would float.
sinks because it has allot of mass
No. The solid state of a metal is more dense than its liquid state, so it sinks.
When it sinks.
All pure metal sinks, only by entrapping air in waterproof compartments can you make it (ships) float.
Not at all. A small pebble and a giant boulder both sink, but a small feather and a giant battleship both float.
Paperclips sink in water because they have a higher density. Unlike wood, a paperclip will sink not float.
The size of the boat is equal to the water displaced by the boat. This means, if the boat is bigger then its weight, the boat will float. If the boat is smaller than its weight, it sinks. This is why metal ships are so big.
