Lili and Beni sit at the table. A big bowl of clean, cold water sits in front of them. Dot, the yellow duck, watches.

Here comes the apple. We put it in. We look. The apple floats! Dot floats too. It rocks. It makes waves.

Next, the stone. We put it in. We look. The stone sinks! Down to the bottom. Silence.

Then, the leaf. We put it in. The leaf floats. It is light. It hovers.

Now, the spoon. We put it in. The spoon sinks! It clinks. Lili laughs.

Beni says, "More! More!" Next, a cork. We put it in. The cork floats! Dot claps. Splash!

Now, a red magnet. On the table are a key and a paper clip. Lili pulls the magnet. It sticks to the key. Snap! It sticks to the paper clip. We pull. It comes with us.

The magnet does not stick to the apple. It does not stick to the leaf. It does not stick to Dot. Beni says, "Funny!" Lili says, "Interesting!"

We look. We ask. We try. The water shows. The magnet shows. Today we experiment. Tomorrow again! Hurray!
