Chapter One

The Science Fair Surprise

"Yes!" I cheered. "Our science fair project is up and ready to roll!"

"Awesome!" my twin sister, Ashley, said.

It was one day before the Orange Elementary School science fair. Kids from every grade were setting up their projects in the gym.

"Check it out, Mary-Kate," Ashley whispered to me. "Here comes the judge."

I glanced up from our exploding-volcano project. A man with gray hair and a large mustache was heading our way. It was Mr. Snyderbush — our science teacher and one of the judges for the science fair.

"Hello, Mary-Kate. Hello, Ashley," Mr. Snyderbush said. He pushed his wire-rimmed glasses up the bridge of his nose. "Is that an exploding volcano I see?"

"Not just any exploding volcano, Mr. Snyderbush!" I pointed out. "Our volcano spews stinky lava."

Mr. Snyderbush studied our volcano. It was molded out of papier-mâché with a small crater dug into the top. Hanging over it was a tiny glass bottle filled with our top secret stink formula.

"How stinky is it?" Mr. Snyderbush asked.

"Nine out of ten on the pee-ew scale!" Ashley answered.

"When real volcanoes spew, they smell like sulfur, the stuff that's in rotten eggs," I told Mr. Snyderbush. "So a stinky volcano is a realistic volcano!"

"That's absolutely correct!" Mr. Snyderbush said. "How did you get the idea for a superstinky volcano?"

Ashley squeezedher nose. "From our brother, Trent's, gym socks," she said.

"I see," Mr. Snyderbush said with a smile. "Keep up the good work, girls."

Ashley and I gave each other a high five as Mr. Snyderbush walked away.

"Our volcano is a hit, Ashley!" I exclaimed.

"Don't make room for that first-place trophy yet," Ashley warned. "We're up against some stiff competition."

"Really? Like what?" I asked.

Ashley pointed over my shoulder.

I whirled around. Two roller skates were whizzing by with no feet in them!

I gasped. "Whose experiment is that?"

"I'll give you two guesses." Ashley nodded in the direction of Dewey and Darcy Mills.

Dewey and Darcy were twins, just like us! They were also the smartest kids in the fourth grade.

"How do you like our self-rolling roller skates?" Dewey asked as he and Darcy ran over to us. "All you do is put them on — and the skates do the rest."

"You can control them with this remote!" Darcy explained. She held up a small black box with an antenna sticking out of the top. Then she threw back her head and began to sneeze. "Ah-ahh-choo!"

"Gesundheit," Ashley and I said together.

"It's the hamster." Dewey sighed. He pointed to the hamster project at the table next to ours. "Darcy and I are allergic to fur."

"That's why we can't ever have a pet," Darcy said, sniffling.

"We just solved a case with mysterious sneezing in it," Ashley said. "'The Case of the Mall Mystery'!"

Ashley and I run the Olsen and Olsen Detective Agency out of the attic of our house. We solve all kinds of mysteries.

"Pet allergies are a bummer," I said. "I couldn't imagine life without our dog, Clue!"

Clue was our silent partner. She helped us sniff out clues on lots of cases!

As the Mills twins ran back to their table, Ashley and I checked out the other projects. On the far side of the gym we found our friend Tim Park layering food in the shape of a pointy tower.

"Hey, Tim! What's that?" I asked.

"It's a food pyramid!" Tim explained. "It shows how to build a healthy diet by eating different kinds of food every day."

I smiled at Ashley. More than anything Tim loved to snack. No wonder his project was about food!

Ashley studied the chart next to Tim's pyramid. "This says that the bottom layer should be breads and cereals, " she said. "You have jelly donuts there."

"They were easier to stack than cereal," Tim said. "And a lot tastier, too!"

"Don't get any ideas," I warned him. "You can't touch those donuts until after the science fair is over."

"I won't eat them!" Tim sighed. "It's those ants I'm worried about."

"Ants?" Ashley asked. "What ants?"

"The ants from Peter Belsky's ant farm," Tim said. He pointed to the table behind him.

Peter Belsky stood in front of a clear plastic tank filled with sand — and an army of hardworking ants.

Peter brushed some dirt off his sleeve. He was always messy. He spilled part of his lunch every day, and he was always being grounded for not cleaning his room.

"Cool project, Peter," I told him.

"Thanks. I'm just glad I got this ant farm here in one piece," Peter said. "Yesterday I dropped it and spilled sand and ants all over my room."

"If the ants escaped from the tank," Tim asked, "how did you find them all?"

"Luckily there was a three-day-old slice of pizza under my bed," Peter said, "and the ants headed right for it!"

"Yuck," Ashley said. She peered into the tank. "Why are those ants carrying cabbage leaves up that hill?" she asked.

"They're worker ants," Peter explained. Then he sighed. "I wish they'd work at cleaning my room."

Tim tugged my sleeve. "Hey," he said. "What's that?"

I looked in the direction Tim was pointing. In the corner stood a tall silver box big enough to stand up in. The box had a sign hanging on it that read: TREMENDOUS TIME MACHINE!

"Let's take a closer look," I told Ashley and Tim. The three of us hurried to the machine. We saw a door on one side of it. Next to the door was a lever that could be pointed to four different time periods: The Stone Age, the Roman Empire, the Middle Ages, and the...

My girls loved 'The Case of the Slam Dunk Mystery' and 'The Case of the Surfing Secret', but the series seems to be going down hill. (New writers?) I'm particularly upset by the questionable morality of Mary-Kate's science fair project, in which she clones herself to make a third 'twin.' Have the liberal media now defiled even dear Mary-Kate and Ashley with their immoral agenda? Please let us return to the days of 'The Case of the Cheerleading Camp Mystery.'
