Plaster of Paris
Plaster of Paris is like magic mud that can harden into a rock-like material when mixed with water.
It's made from a type of mineral called gypsum, which is found in the ground.
When we mix the powder of plaster of Paris with water, it starts to change chemically and becomes a thick paste that we can use for different things like making casts or molds.
Once the plaster is mixed with water, it dries quickly and becomes very hard in just a few hours, which is why it's commonly used for things like making casts for broken bones – it can hold the bone in place while it heals.
Plaster of Paris can also be used for art projects like making sculptures or masks. We can pour the plaster into a mold and when it's dry, we can remove it and paint or decorate it!
It's important to remember that plaster of Paris can be messy and we should always follow the instructions carefully to use it safely.
