Put some water on it and let it stay damp for several days.
Type C gypsum board meets and exeeds the fire resistance requirements of a type x board. It has mineral additives in the gypsum core that expands when exposed to heat. This expansion holds the board together longer during fire exposure. It is referred to by the Gypsum Association as "Improved Type X" board.
Gypsum wall board, also known as drywall, offers benefits in construction projects such as fire resistance, sound insulation, ease of installation, and cost-effectiveness.

If gypsum board gets damp, it can lead to several issues, including mold growth, deterioration of the board, and a weakening of its structural integrity. The moisture can cause the paper facing to peel away, and the core can become soft and crumbly, compromising its fire-resistance properties. It's essential to dry or replace damp gypsum board promptly to prevent further damage and health risks.
as you put stuff on the science board like A Demetria of your project it gets better.try this and its up to a pass of first place
It is to acknowledge the people that helped you with your board.
For your project, you should use standard drywall, also known as gypsum board. It is versatile and commonly used for interior walls and ceilings in residential construction.

That depends upon location. Tiles can be installed on a gypsum board wall or ceiling. (But make sure that the tiles are well grouted; if moisure gets past the tile into the gypsum board, it will be damaged.) Floors require greater strength - but then, you wouldn't normally have a gypsum board floor, with or without tile.
