Make a tornado in a jar

Tornado in a jar

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.
