Emmy was doing her homework.
"I have to do a science experiment," she said.
"Make a volcano, Emmy!" Oliver said.
"Volcanoes are boring," Emmy said.
"They're just vinegar and baking soda."
"You could put something else in the volcano," Harry said.
"Like what?" asked Emmy.
"Some kids use ketchup instead of vinegar," Harry said.
"That makes red lava!"
"Cool!" said Emmy.
Aunt Judy looked worried.
"Will it make a mess?" she asked.
"Mom might get mad."
"Mom won't mind!" said Emmy.
"Mom loves science experiments!" said Oliver.
Emmy made a clay mountain.
She made a hole in the top.
Then she mixed ketchup with some soap and water.
Emmy poured the mixture into the volcano.
"Let's put some glitter in too!" she said.
Finally she added baking soda.
Everyone waited.
The volcano steamed.
Then it exploded!
Red lava spilled out of the volcano.
It dripped all over the floor.
Glitter sprayed everywhere.
"That was not boring!" Emmy said.
Oliver clapped.
Harry laughed and laughed.
"What's going on?" someone asked.
Everyone looked up.
Mom stood in the doorway.
She was frowning at the mess.
Aunt Judy gulped.
"We were doing a science experiment!" Emmy said.
She grabbed a sponge.
"But now we're cleaning up!"
