FORT WAYNE, Ind. (21Alive) -- In this week's episode of Cool Science Monday, Martin Fisher from Science Central will talk about corrugated plastic and sound.
One was a corrugated plastic straw from a cup, the other was a long corrugated tube. When Martin blew air slowly through the straw, it caused a vibration, but the vibration was slow, and the sound was deeper.
When he blew harder, the air passed through faster, caused faster vibration and a higher sound.
Same thing, when he swung the tube around my head; If he swung slowly, it vibrated slower and had a lower sound. The opposite occurred if he swung the tube faster.
