The Jelly That Would Not Set

The hammer rang once. A spark jumped off the anvil and did not go out. It waited. They followed.

Tap, tap, on the kitchen window. The party was tomorrow.

The jelly was still runny.

"I promise it will wobble!" said Lan. She had told all the guests.

"It's the fridge! I can name it," said Inkling. "Move it!"

"Then which change did it?" said Compare. Compare was a raccoon with two jars.

"Change one thing at a time," said Compare. "Keep everything else the same."

Three suspects. The fridge. The water. The fresh pineapple.

Three small bowls. Bowl one: a new fridge. Bowl two: water, measured. Bowl three: no pineapple.

That night, Lan could not sleep. She had promised too soon.

In the morning, bowl one was runny. Bowl two was runny. Bowl three wobbled!

"Look at the pieces first," said Patternby. The runny jelly was runniest by the pineapple.

"Pineapple is bad!" said Inkling.

"I cut at one pattern, every time," said Clippa. Snip!

Fresh pineapple cuts the jelly. Heated pineapple does not.

Bà Tư opened a tin. Tinned pineapple was heated. It set!

Lan made the party jelly again. She did not promise. She waited. She poked it.

Wobble, wobble. "Ready," said Lan.

The spark dimmed to a warm dot and settled back on the anvil. The Green was just the Green again.

Back on the Green

Lan's two paper boats both sank. Was it the paper, or the wind? She changed just one thing.

Tell the story back to someone. Why did they make three bowls?

The Honest Page

Which parts of this story are true, stretched or made up?

True

  • Fresh pineapple stops gelatine jelly from setting. Something in it, called bromelain, cuts up the jelly's strands. Source
  • Heat stops it working. Tinned pineapple has been heated, so it does not stop jelly setting, and nor does fresh pineapple that has been simmered first. Source
  • A fair test changes only one thing at a time and keeps everything else the same, so you can tell which change made the difference. Source
  • Three suspects, three bowls, one change in each.
  • Fresh kiwi fruit and papaya do the same to gelatine jelly. Jelly made with agar, which comes from seaweed instead of gelatine, sets even with fresh pineapple. Source

Stretched

  • In the book, Clippa's scissors stand for the thing in pineapple that cuts the jelly. What we simplified: There are no real scissors. Bromelain is too small to see; it works like a cutter that only cuts at certain places, which is why Clippa's one-pattern scissors are a fair picture.

Made up

  • The talking raccoon, owl and crab are made up, and so is Bà Tư's party. Ask a grown-up before using the stove.
