undressed and brushed his teeth. Before he got into bed he opened the window and looked out. Above him the sky was brilliant with stars. Somewhere among those glowing, twinkling points of light one of Professor Bullfinchâs shoes sailed, on and out, away from the familiar earth.
âA ship to the stars,â Danny murmured to himself.
Then, with a chuckle, he jumped into bed and, before his imagination could begin to work, he was asleep.
CHAPTER SIX
An Odd Duet
The next day began badly for Danny.
In the first place, he was so excited by the events of the night before that, once he got his eyes properly open, he didnât want to go to school, knowing what would be happening at home. It was with difficulty that Mrs. Dunn bundled him out of the house. When he got to school, he was ten minutes late.
Then, as if that werenât enough, he discovered that he had forgotten his hundred sentences. He couldnât even remember where he had left them. Miss Arnold did her best to be patient, but in the end she said, âIâm sorry, Dan, but youâll have to learn to take assignments like that more seriously. Tomorrowâno, tomorrow is Saturdayâvery well, Monday, I want to see those sentences and another fifty saying, âI must remember to bring in my work.â â
When he started for home at three oâclock, Danny felt as if all the sorrows of the world rested on his shoulders. Joe Pearsonâs first words did nothing to make him feel better.
âGosh,â Joe muttered, as they walked up a tree-shaded alley together, âthat Miss Arnoldâwhere some people have a sense of humor, sheâs got a sense of gravity.â
âGravity?â Danny said with a start. The word reminded him at once of the Professorâs discovery.
âYou know what I mean, she always takes everything so seriously.â
âOh, sure, sure.â Danny bit his lip, remembering his solemn promise to keep silence.
Joe moodily kicked at a stone. âOf course, itâs your fault too, Danny. You always have your feet off the ground.â
âHuh?â
Joe nodded. âTake it easy. Remember, what goes up must come down.â
âUrp!â said Danny.
âLook at that, now. A hundred and fifty sentences! And on a weekend too.â
âListen, Joe,â Danny began. âIâlisten, supposeââ
âSuppose what?â
Danny gulped. He had given his word, after all, on his honor as a scientist.
âNothing,â he said.
Joe looked sideways at him. âBoy, youâre really dizzy. See that? Nothing but trouble. It all started with that spaceship stuff yesterdayââ
âEep!â Danny couldnât help himself. Then he clamped his lips shut. Luckily Joe wasnât paying attention.
ââand this is where you wind up. Whatâs the matter? Did you get into trouble last night when you got home?â
âTrouble? OhâIâwhyââ The effort of trying not to talk about the anti-gravity fluid, when every word brought it to mind, made great beads of sweat stand out on Dannyâs forehead.
âHey, I gotta run,â he blurted at last. âMy mother promised to bake me if I didnât get home.â
âWhat?â
âI mean, sheâs going to lick a cake. I meanâanyway, Iâve just got to go. I have to do about a thillion mingsâI mean a million thillsââ
He wiped his face. âSo long, Joe. See you tomorrow, maybe,â he gasped.
Then he ran for home, leaving Joe staring, openmouthed, after him. But for once Danny couldnât spare the time to worry about what his friend thought; he was too busy wondering what was going on in the laboratory.
The lab, when he poked his head cautiously in at the door, was a peculiar sight.
Almost half of the equipment was stuck to the ceiling. To some of the pieces long wires leading to rows of batteries on the tables were
