A tornado is air which is spinning very fast. It is made by a special type of thunderstorm called a supercell.
What you will need:
- A clear jam jar or similar see-through container with a screw-on lid
- Washing-up liquid or liquid soap
- Food colouring
What to do:
Fill up the container with water then add a few drops of the washing-up liquid and a few drops of the food colouring. Tightly screw on the lid.
Swirl the container around in a circle lots of times and then stop. Inside you should see what looks like a tornado. It will slowly disappear as it reaches the top of the container.
Tornadoes in the real world are made in a similar way, when cold and warm air combine and spin.
