We can get paint and dyes from pigment, but Nobel believes he can made it into explosive. Though his parents didn't know what came over to him, they are supportive to him. Every time he don't eat anymore, they help him dispose of the food.
One day, when he mixed the chemicals in two flasks, the house vanished. He was so excited because it substantiated his idea. His parent suppressed their sadness and said "you are so~ good".
After the invention, he made an itinerary of Europe to tell others about it. And now it's prevalent to respect Nobel as a great scientist.
