beaker.
âBetter not,â I warned him. âYou can get into real trouble if you donât know what youâre doing.â
âIâm not planning anything major,â Colin said. âJust a little stink bomb.â
âI donât know,â I said. âMy mom and dad told me notââ
âWe can set it off upstairs,â Colin interrupted. âDonât you want to see your sister choking and gaggingâright in front of that guy she likes?â
That would be pretty funny. At least until my parents found out.
âWhereâs the manual?â Colin asked, digging through the box.
âI thought you knew how to make one!â I replied.
âNo. No, I donât,â Colin admitted. âBut the instructions must be in here somewhere.
âOh, sure,â I said sarcastically. âJust look under S for stink .â
Colin found the instruction booklet and flipped through it, shaking his head. âNothing here,â he muttered.
âCome on,â I said. âLetâs go out. We can go to the mall or something.â
âNo. Letâs stay here. We donât need instructions. It canât be that hard to make a bad smell,â Colin declared. âYour sister does it without even trying.â
I laughed. Colin can always make me laugh. Thatâs one of the reasons weâre best friends.
Colin tipped the test tube of purple crystals over the red liquid.
âColin. Donât do it,â I warned.
He ignored me.
He tipped the test tube some more.
âColin! You donât know what youâre doing!â I yelled.
The purple crystals began to tumble out.
I looked at the labels on the test tubes. âNot the red and the purple, Colin! Not those two!â I screamed. âYouâll blow up the house!â

I snatched up the beaker.
The purple crystals spilled from the test tube and scattered all over the worktable.
âYou canât mix chemicals without knowing what will happen, Colin! Those two could have caused an explosion!â I yelled.
âOh,â Colin replied. âDoes that mean no stink bombâjust because youâre scared of blowing up the house?â
I laughed. I couldnât help it. Like I said, Colin knows how to crack me up.
âOkay, okay. No stink bomb.â Colin gave in. âLetâs go to the mall.â
We started to pack up the chemistry set. âHey!Whatâs this?â Colin asked as he tried to shove the test tube rack back into the carton.
He pulled out a single sheet of paper from the bottom of the carton. âHa! Is this good enough for you?â he exclaimed.
I peered over his shoulder and read the paper. Directionsâdirections for how to make a stink bomb. Weird.
The instructions were handwritten on a bright orange piece of paperânothing like the plain white paper the manual was printed on. Very weird.
âLetâs do it,â Colin urged. âWe have all the stuff.â
âWell, okay,â I finally agreed. How could I pass up the chance to embarrass Michelle?
We measured the chemicals carefully and combined them in a clean beaker. âWeâll leave this one out until weâre in position upstairs,â I told Colin. I showed him a test tube filled with yellow powder.
âGood idea,â he answered.
We tiptoed up the stairs and into the kitchen. I peeked into the living room. Jonathan Muller stood by the fireplace, talking about some chess tournament they were organizing.
I spotted Michelle on the sofa. She leaned forward, gazing at Jonathan across the room. The other kids were all focused on Jonathan, too. Perfect.
âCome on,â I whispered. I got down on my hands and knees and crawled into the living room. Crawledto the back of the couch and hid behind it. Colin followed.
âReady?â Colin mouthed, holding out the beaker.
âYes,â I whispered, holding up the test tube. âHold your
