The twister began to move. It skipped and bounced across the fields.
It grew bigger, faster and dirtier as it picked up mud from the ground. Waterspouts Twisters out at sea are called waterspouts. They whisk up water. The tallest one seen was 1. It picked up straw, trees — and even a farm truck. It spun them around in its funnel. Rob sighed with relief when the twister moved away. He thought he was safe. But then the twister changed direction — straight towards him! There was a noise like a rushing waterfall, then — BANG! The barn exploded as if a bomb had gone off inside it. His ears were hurting and he could hardly breathe.
Two minutes later, all was silent. Rob came up from the cellar. Furniture lay smashed on the floor. Most of the doors and windows were gone. Rob felt lucky to be alive. The warm air is sucked up in a swirling column called a funnel cloud. It spins at great speed. Twisters contain the most deadly winds in the world. It can lift up a large truck and smash it to pieces, but leave small objects undamaged.

One twister sucked up some roses and water from a vase. It dropped them in another room but it left the vase on the table. They can be thin, white and wispy. Or they can be big, thick and black.
They can even be red or green! If a twister travels across a muddy field, the mud turns it brown — and very smelly! Some look as if they have a loop or knot in the middle.
