This wonderful Merry-go-round can be made using Margosa pods and Acacia thorns – both available for free in many poor countries. Stand a small branch / stick on a rubber base. Fix a long Acacia thorn or needle on the top of the branch. Poke two Margosa pods at the two ends of a thorn. This assembly of a thorn plus two pods can be perched on the tip of the Acacia thorn. This assembly can also spin very freely. 
Make several such assemblies of thorn plus two pods. Place two such assemblies simultaneously near the ends of the first thorn. You will find that they will be well balanced. Now place two more on the left thorn. This will tilt the system to the left. Now place two more on the right thorn. This will restore the balance once again. 
Now with a straw give the first thorn a spin. Once it gains speed this merry-go-round will keep spinning for a very long time. This zero cost traditional toy has provided hours of fun to children in poor countries.
