The Kingdom of Science will need rations to last them through their voyage to the other side of the world. But Senku, being no professional, burns all the bread he attempts to bake.
Bacteria won't grow if 
there's no moisture in it.
.لن تنمو البكتيريا إن لم يكن به رطوبة
Ohne Wasser können Bakterien
sich nicht vermehren.
Sin humedad,
las bacterias no se reproducen.
Sin humedad,
las bacterias no se reproducen.
Sans eau, les bactéries
peuvent pas se développer,
E senza umidità, i batteri non si riproducono.
Bactérias não crescem 
onde não há umidade.
Без воды плесени неоткуда появиться.
