eyeballs almost popped out. âThereâs recycling, I guess,â she said. âWe could show how itâs good for the earth.â
âBut everyone already knows about recycling,â said Ivy. âWeâre supposed to have a
new
idea.â
They thought some more.
Beanâs dad came into the kitchen. He looked at their thinking faces and sat down at the table next to Bean. âWhatâs happening, kidalunks?â
âWe need an idea to stop global warming,â said Bean.
âEasy,â he said. âGet rid of cars.â
âDad, weâre seven. We donât have cars. We need something we can do for a science fair.â
âOh,â said her dad. He leaned against the back of his chair and frowned. For several moments it was quiet.
Suddenly, he snapped his fingers. âOkay! Got one! You guys can make posters that remind people to turn out the lights! You know, to save electricity. You could have a slogan, like âLights Out When Youâre Out!ââ He smiled at them proudly. âIsnât that good?â
Bean and Ivy exchanged looks. âYeah, Dad,â said Bean. âGreat. Thanks.â
âWell!â he said. âIâm going to go clean out the drains.â
âOkay,â said Bean. Ivy and Bean watched as he left the room. Then they looked at each other and shook their heads. âThat has got to be the most boring idea ever,â said Bean.
âYou know grown-ups,â said Ivy. âThey donât have very good imaginations.â
Ivy and Bean began thinking again.
âWhat if . . .â began Ivy and stopped. She stared at the refrigerator. âIce cubes!â
Bean looked at the refrigerator, too. âWhat about them?â
âThinkâhow do you cool down a hot thing?â asked Ivy, âIce cubes! If we could put ice cubes up in the sky, the air would get colder, right?â
âRight,â said Bean. âBut how are we going to put ice cubes in the sky?â asked Ivy.
âWell, in real life, theyâd probably have to drop them out of airplanes, but for the science fair, we could just throw them up in the air to show what we mean.â
Bean slapped her hand on the table. âGreat idea! And easy, too!â
A minute later, they were running out Beanâs back door with all the ice cubes theycould find in the freezer. The next minute, they were running back inside to get a thermometer from the bathroom closet. And the minute after that, they both stood on Beanâs trampoline, holding bowls full of ice cubes.
âThe higher we can throw them, the more theyâll cool down the weather,â Ivy said, looking at the sky.
âOn your mark,â said Bean. âGet set. Go!â Together, they began to bounce, higher and higher, higher than they had ever been before.
âI can see my house,â yelled Ivy.
âI can see the North Pole!â shouted Bean. But that reminded her of what they were supposed to be doing. âYou ready?â
âYup.â Ivy scooped up a handful of ice. âWe have to do it quick.â
Together, they boinged as high as they could get and hurled the ice up into the air. âQuick, quick, get the thermometer!â yelled Bean. Flinging her bowl to the ground, Ivy snatched the thermometer and bounced up again, waving it in the air.
âItâs definitely cooler up there,â said Bean, collapsing onto the trampoline. âWhatâs it say?â
Ivy slowed down and peered at the thermometer. âI donât know,â she said. âIt looks like 37.â
âThatâs cold,â said Bean. âI can feel it. LookitâIâm shivering.â Ivy looked.
Beanâs backyard gate swung open. Nancy and her friend Mischa came in, giggling. They stopped when they saw Ivy and Bean. Nancy looked at the lawn. âWhy is there ice all over the backyard?â she asked.
Bean would never have
