The large Spirelli, from Grimm's.
 
With a 'whizz' and a 'hum,'  the little wooden, rainbow, discs dance down the twisty metal trail!  The Spirelli can be a magic wand, a musical instrument, a means of calling some calming time for a classroom or home, or simply for the joy of it! We have seen little toddlers, preschool teachers and parents with autistic children become mesmerized by the flying discs of the Spirelli.
