Sense and Sensibility

THE SENSES AND HOW WE USE THEM

SOUNDS INTERESTING – THE SCIENCE OF HEARING

We see how sound is made, how it changes in pitch, how we hear it; how it is transmitted through the air and other materials, how resonance works.

Magic tricks

All tricks are self-working, and easy to do at home

  • Birth of Sound – making sound from a ruler.
  • Singing in the Drain – finding resonance in solid objects.
  • Whining Wine – glass harp from wine glasses.
  • Harmonious Spuds – swing moves between them.
  • Bottle Blow – resonance makes it swing better.
  • Small Ben – Big Ben from a coat hanger.
  • Ventriloquism – why it works.

SIGHTS FOR SORE EYES – THE SCIENCE OF SEEING

These tricks demonstrate how light travels through the air, and how glass bends it. With the aid of optical illusions we study how vision works – there’s more to light than meets the eye.
