Aya has a small toy.
The toy is a paper parachute.
The paper is very thin.
It falls down too fast.
Aya wants a slow fall.
She has many kinds of paper.
She has a new idea.
She wants to test every paper.
She wants to find the best paper.
Aya looks at all the papers.
They are all very different.
Some paper is thin and light.
Some paper is thick and heavy.
Aya is ready to start.
She puts the papers on a table.
Now she starts the test.
Aya is very happy.
