Hooked on Science: Sound Blaster

INGREDIENTS

• 18oz Plastic Cup
• Metal Slinky
• Pipe Cleaner

INSTRUCTIONS
STEP 1:  Hold the top ring of the metal slinky to the bottom of the plastic cup.

STEP 2:  Gently swing the metal slinky back and forth, allowing the slinky to hit the floor, and observe.

EXPLANATION
Sound is vibrations moving through matter. As you gently swing the metal slinky back and forth, allowing the metal slinky to hit the floor, it vibrates. Those vibrations move through the metal slinky to the cup. The cup amplifies the vibrations allowing you to hear what sounds like Han Solo’s blaster.
