The following passage is from J.W. von Goethe's "Faust", it is taken from the scene where Dr. Faust and Mephisto ask the witch for a spell of youth.

See how it’s done!
Make ten of one,
and let two be,
make even three,
then you’ll be rich.
Cast out the four!
Now heed the witch:
from five and six
make seven and eight,
and now you’re done;
Then nine is one,
And ten is none.-
That is the witches’ one-times-one.

When you take a (magnetic) board with a 3x3 grid and move the numbers according to above rhymes you end up with a magic square.

This is a beautiful effect on its own, or you can use it as a lead in to several bizzare magic effects using strange artefacts and poisonous liqids.

Enjoy,

Ingenious, now if I could just translate the dang poem correctly!

Here is the original German (no need to translate yourself):

Du mußt versteh'n,
Aus Eins mach Zehn.
Die Zwei lass geh'n.
Die Drei mach gleich,
So bist du reich.
Verlier die Vier!
Aus Fünf und Sechs,
So sagt die Hex,
Mach Sieben und Acht,
So ist's vollbracht:
Und Neun ist Eins,
Und Zehn ist keins.
Das ist das Hexen-Einmaleins!
