Im August wurde mal wieder eine Installation eingeweiht, die auch für die kleinen Forscher zum “ah-ha”-Erlebnis wird. Zu finden ist das Schallrohr direkt an dem neugestalteten Spielplatz hinter der Baltic Schule.
Was auf den ersten Blick wie eine große Kabeltrommel aussieht, ist ein langes aufgewickeltes Rohr mit einer Sprechmuschel und einem “Kopfhörer”. Wenn man in die Muschel spricht, legt man unweigerlich sein Ohr an den “Hörer”. Spricht man in die Muschel denkt man erst das nichts passiert – aber es passiert doch etwas. Man muss nur einen Augenblick Geduld haben, denn dann hört man seine “Nachricht”. Der Schall breitet sich mit seiner “Schallgeschwindigkeit” aus und durch die Länge des Rohres (überschlägig 125 m bei 343 m/Sek.) braucht es ca. 1/3 Sekunde bis der Schall auf das Ohr des “Senders” trifft. Eine Zeitverzögerung, die man schon wahrnimmt.
Leider findet sich auch an diesem Objekt keine Info-Tafel mit einer Angabe weder wofür es steht, noch was es bedeutet.
