When she was finished, Carla closed the bag and returned to its place. Now she looked at Henry. Carla realized that Henry was staring at the iron and the few remaining coils of string.
“But what shall we make with this iron and strings?” Carla said, she questioned Henry's opinion.
“We can make a slingshot with this iron. Stronger than wood?” Henry said, he was trying to make a suggestion.
“Possible. I've never measured which is stronger between an iron and a wooden slingshot,” said Carla, she gave Henry the answer.
“Yes, I'll do it after this. We need only two slingshots. For you and me,” Henry said, he told Carla his decision.
Carla watched Henry who was enthusiastic about making a slingshot out of iron. She tries to understand how Henry made it.
After observing for a long time, Carla finally understood. She tried to take iron and some strings. When she was about to follow Henry's movements, Carla turned to look at Henry's face.
