This object was the start of the series “Magical Moments”.
The main components are three rotating elements with pointers.
When these three separate elements rotate (every so often), the three arrows can point in any direction of the compass, but there will come a time when all three will – magically! – be pointing in exactly the same direction. That means ‘Aether’ has been found ! and is strongest in that direction – hence the name ‘Aether Meter’. 😉
Dimensions: 28 cm wide, and about as high and deep.
