This is fun an easy to assemble at home.
All you need is some paper tubes like the inside of a toilet paper roll or gift wrapping and some tape.
Tape the rolls together and stick it to a window or wall.
We used pom poms as they have a nice soft texture. You can also use small balls like bouncing or ping pong balls, or even little stones.
Let your child throw the pom pom down the tube. It seems so simple but is lots of fun. Younger children might take a while to realise that they are falling out the bottom. I like putting a container at the bottom to catch them so that they don’t fall and roll all over the floor.
