Experiment:

Question:

How does Ms. Santa have to position the three objects to observe the phenomenon shown in the movie?

A) Put the CD cover, glass and candle in a row.

B) Line up the glass, CD cover and candle.

C) Line up the candle, glass and CD cover.

D) Line up the candle, CD cover and glass.

Advice of the day:

The eye of the observer is set as the first fixed point, the listed objects then follow. The four objects do not have to be positioned exactly in a line, but can be moved a little to the right or left if necessary. The options A and C or B and D are therefore not identical.
