The kid says NOW FOR SOMETHING SUPER.
WATER AND HONEY ARE BOTH LIQUID.
BUT ARE ALL LIQUIDS THE SAME?
LET'S POUR THEM ON THE STARS TO
FIND OUT.

A kid pours water on a star-shaped tray.

The kid says THE WATER IS MOVING QUICKLY.
WILL THE HONEY MOVE QUICKLY?

The kid pours honey onto another tray.

The kid says NO.
THE HONEY IS MOVING SLOWLY.
DO THEY FEEL THE SAME?
THE WATER IS SPLASHY...
AND THE HONEY IS STICKY.
SO, HONEY IS SLOW AND STICKY...
AND WATER IS FAST AND
SPLASHY.
SO, NOT ALL LIQUIDS ARE THE
SAME.

A song plays that goes THE WORLD IS FULL OF VARIETY
LOOK AROUND, WHAT CAN YOU SEE
