Making Fun
Trevor’s father promised him they’d go to Game World together after work. But it was almost 7:00 pm and his dad was still working.
“Hey, little bro.” Anthony touched Trevor’s shoulder. “Are you going to sit there and be
“He is always breaking his promises. I don’t want to go to Game World anymore.”
“Good, because I wasn’t going to take you to Game World. I have something else in mind.” Anthony asked Trevor to follow him.
Trevor got up and walked into Anthony’s room. Then Anthony picked up a box on his desk. “Today we are going to make bouncy balls (弹跳球).”
“No way. You can’t make those things yourself.” Trevor loved playing with bouncy balls. He had his own (自己的)
“Oh really? I guess you don’t want to
“I didn’t say that,” Trevor said.
Anthony opened the box, removed two cups and filled them with water. “Now, put the colors into the molds (模具).”
“Aren’t you making one, too?” Trevor asked.
“Sure.” Anthony came close to Trevor and said, “My ball will bounce higher than yours.” He smiled.
“You’re on!”
Trevor used blue and green for his ball. Anthony
Anthony removed the molds and placed them on the table for ten minutes. Trevor couldn’t wait to see if it
“Okay, it’s time.” Anthony removed the balls from the molds and handed Trevor his blue and green ball.
Trevor looked at the ball. They were like the ones in his collection. “Think they really bounce?”
They each bounced their balls to the other. “Whoa! They work!” Trevor bounced Anthony’s ball back to him. “This is cool.”
“See,
“You’re right. Let’s make some more balls.”
