butt on the cold cellar floor.
âOh,â Nilly said. âLisa, are you okay?â
âYeah,â she said, a little dazed as the professor helped her back onto her feet. âWell, Iâd call that some pep!â
Nilly laughed out loud. âWell done, Doctor!â
âThank you, thank you,â the professor said. âI think Iâll conduct a little test myself â¦â
The professor took half a teaspoon and counted down. At zero there was another bang, but this time Lisa was careful to stand by the door.
âWow,â the professor said, picking up the plant, which didnât have petals on it anymore. âI think weâll do the next test outside.â
They poured the powder into a cookie tin and brought it outside.
âGive me the teaspoon,â Nilly said.
âCareful with the dose ⦠,â Doctor Proctor started to say, but Nilly had already gobbled up a full teaspoon.
âI feel a tingling in my stomach,â said Nilly, whowas so excited that he was whining and jumping up and down.
âSevenâsixâfive,â the professor counted.
When the bang came, all the songbirds in the professorâs pear tree took off and flew away in alarm. And this time it wasnât Lisa but Nilly who got knocked over and disappeared in the tall grass.
âWhere are you?â Doctor Proctor yelled, searching in the grass. âHow did it go?â
They heard a gurgling noise and then Nilly popped up, totally red in the face from laughing.
âMore!â he yelled. âMore!â
âLook, Professor!â Lisa pointed. âIt ripped the seat of Nillyâs pants!â
And indeed it had. Nillyâs pants were practically torn apart. The professor looked at the results with concern and decided that they should stop the testing for today. He asked them to search for his lawn furniture, which was in the grass somewhere,and then went inside. When he came back out, he brought bread, butter, liverwurst, and juice. Lisa had found the lawn furniture, and while they sat in the crooked white-painted chairs and ate, they contemplated what the invention could be used for. The professor had the idea of trying to sell the powder to farmers. âThey could eat a half teaspoon of fart powder,â he explained, âand hold the sack of seed grain in front of the ⦠uh, launch site. Then the air pressure would spread the seeds over the whole field. Itâll save a ton of time. What do you guys think?â
âExcellent!â Nilly said.
âTo be completely honest,â Lisa said, âI donât think people are really going to want to eat food that comes from seeds that have been farted on.â
âHmm,â the professor said, scratching his mop of white hair. âYouâre probably right about that.â
âWhat about making the worldâs fastest bicycle pump?â Nilly yelled. âAll you have to do is take ahose, fasten one end to your butt and the other to the valve on the bike tire, and then ⦠kaboom! The tire is filled in a fraction of a second!â
âInteresting,â said the professor, stroking his goatee. âBut Iâm afraid itâs the kaboom thatâs the problem. The tireâs going to explode too.â
âWhat if we use the fart powder to dry hair?â Lisa suggested.
Nilly and the professor looked at Lisa while she explained that the whole family could draw straws, everyone from the littlest to Grandma, to see who would eat the fart powder after everyone had showered in the morning. And then everyone else could just stand behind that person.
âGood idea,â said the professor. âBut whoâs going to dry the farterâs hair?â
âAnd what if the blast knocks Grandma over and she breaks her hip?â Nilly said.
They kept tossing out one suggestion afteranother, but all of the suggestions had some kind of annoying drawback or other. In the
