Dr. Stone Wiki

Beautiful Science (美しい科学 Utsukushī Kagaku) is the forty-fourth episode of the Dr. Stone anime, and the ninth episode of the third season.


The only Perseus crew who managed to escape the petrification beam were Suika (thanks to Ryusui) and Ginro who was in the sea. With the ship occupied by Ibara and his men, the two received Kohaku's desperate message to get and deliver the Mobile Lab to Senku and the others on shore. Meanwhile, Senku continues his operation to infiltrate the island's inner palace and obtain the petrification weapon. As such, the science operation on Kohaku's beauty makeover begins!

Plot Details[]

Ginro attempts to flee the ship from cowardice but when he sees Suika bravely creating a distraction, he is guilted into helping tip the lab overboard and reunite with Senku. To throw off the guards, Senku convinces them the lab was a giant animal by combining sulfur with amine from rotten shellfish and skatole from jasmine to create the smell of dung. Hiding the lab in a cave, Senku makes shampoo by mixing coconut oil with salt, sodium hydroxide, and sulfuric acid; hair conditioner from coconut oil, honey, and lemon; makeup from coconut oil with crushed mica and other colored rocks; lipstick from coconut oil, honey, and crushed insects; and perfume from lemon, jasmine, and vanilla. Kohaku is transformed from wild gorilla into cute beauty. To increase their chances, Amaryllis uses the makeup to disguise Ginro as a cute girl too. Ibara selects all three of them and a dozen other girls to be presented to the Master for choosing. Moz narrowly prevents Kohaku from breaking the oblivious Ibara’s fingers and, excited by her secret strength, promises to fight her himself when she causes trouble at the palace. Senku begins plotting how to steal the petrification weapon.
