The Nutcracker pas de deux
The Andante maestoso movement used a device on the stage called a reika. This was a small platform or wagon set in a track. It was operated under the stage. In The Nutcracker, the Sugar Plum Fairy stepped upon a scarf that Prince Coqueluche had placed on the reika. The Prince pulled the scarf and, as the reika was moved from one side of the stage to the other, it seemed that the Sugar Plum Fairy was lighter than air.
