Revealing ancient life. Paleontologists use plaster casts to study fossils and prehistoric footprints without damaging the delicate originals. Scientists can pour plaster directly into fossil holes and footprints to see exactly what the creature looked like or how it walked.

Copying artwork safely. Museums use plaster casts to make copies of famous sculptures and statues so the real ones stay protected and people everywhere can see them. One famous example is the David by Michelangelo, which has many plaster copies around the world.

Capturing memories. Parents sometimes make plaster casts of their baby's hands and feet as a keepsake, creating a permanent record of how tiny they were. This lets families hold onto a special moment as their child grows.

Recording buildings. Architects and historians use plaster casts to preserve details from historic buildings, like decorative trim or broken statues, so they can study and restore them accurately later.
