Special Materials have special properties usually only found attached to that material. This can include anything from making particle effects to affecting gameplay and characters somehow.
The Peach Floaty is a material that ascends up when not somehow connected to another object (string or glue). The weight Peach Floaty can lift up depends on the Peach Floaty's size, and the other material's type and shape. The material is grabbable and affected by explosives. The floaty may also be able to carry the sackperson if the sackperson grabs it.
Unlike the Peach Floaty material, which ascends up, the Pink Floaty is suspended in midair, and won't move unless something makes it move like a sack person. It is affected by explosives and is grabbable.
Dark Matter is the all around most useful material. It floats without flying off into the distance or falling! Plus, If you make a small piece of it and glue any materiel over it and it looks as if it's floating! There is a glitch associated with it. If you shrink it enough and you place or smear it, it will come out invisible. Note it does not work in grid.
White Matter is a variation of Dark Matter introduced in LittleBigPlanet 2. Apart from being white and having much sharper edges, compared to Dark Matter's round edges, it is more-or-less identical in functionality.
The Dissolve Material is a material that possesses a special mechanic to dissolve when activated by logic or switches.

A non-solid material introduced in LittleBigPlanet 3 that pushes objects and players around.
A non-solid material introduced in the SpongeBob SquarePants Premium Level Pack. It behaves similarly to Global Water, in that characters can swim in it (excluding Big and Small Toggle, who sink or float in it respectively), and buoyant objects float to the top of it. The only difference between the Floaty Fluid and Global Water is that players can stay in Floaty Fluid without drowning unless it is changed in a level with custom logic. Players can tweak it to have a current that pushes players and objects in a specific direction, similar to the Wind Material.
In all LittleBigPlanet games preceding LittleBigPlanet 3, Materials would be created with four different levels of thickness: 3 Fat, 2 Fat, 1 Fat, or Wafer Thin. Wafer Thin shapes will fall between larger objects. In LittleBigPlanet 3, there are 16 layers as opposed to the three layers of prior games, but go under the same rules.
