These flying elf hats are great fun for younger children in the run-up to Christmas. They are quick and easy to set up but keep kids busy for a long time. All you need is an empty milk container, green and red paper and tape.
The same activity is often called rocket mouse, as traditionally, the cone is made to look like a mouse, not an elf hat.
Green and red paper or card
Milk container – clean and empty
Felt tip pens
Create a cone with the paper and tape. I added some stripes to mine and a small pom pom to make it look like an elf hat.
Place the elf hat cone on top of the milk container.
Use both hands to squeeze the milk container. The elf hat will shoot into the air!
Why does the elf hat fly?
When you squeeze the bottle, the air inside is forced out through the top. The force of the air against the elf hat cone sends it shooting upwards. The harder you push the sides of the bottle together, the greater the force of the air leaving the bottle, and the higher the elf hat will fly!
Investigations to try
Add a bigger pom pom to the top of the hat. Does it fly as high?
Can you get the hat to land on your head?
What happens if you use a bigger or smaller hat?
