Would you like to make a pretty ballerina walk on a tight rope?
It’s easy! 
Fix two cycle spokes on a piece of wood and stretch a piece of string tightly between them.
Cut a doll from a stiff card sheet.
And cut “V” notches on her feet.
Make a semi-circular arch from a stiff card sheet.
Staple the doll at the centre of the arch.
Separate the legs of the doll.
They should be a little apart.
Now place two magnets back-to-back at the end of the arch.
You will see that the North Pole sticks to the South.
The nice thing about magnets is that you can move them up and down.
This way you can change the balance.
Now gently place the doll on the stretched string. 
You will be surprised to see the Ballerina will balance itself.
With a little push it will sway and dance gracefully.
You can also make the Doll balance on a cycle spoke.
