Echolocation

 

Rue: YOOOOOOOOOOOOOOOOOO!

 

Foxface: Shut up! Let's go!

 

(music starts)

 

Rue: I'll tell you little rap now!

 

Foxface: Science! Science!

x3

 

Glimmer: 39 million in this world are blind

 

Rue: And then someone thought that it would be kind (pause)

to come up with something that would help them find

 

All: Whatever they are looking for even if they're blind

 

Foxface: Daniel Kish; those are the words

he helped 500 children around the world

 

Glimmer: He's been blind since his first year

then he found out he could use his ears!

 

Chorus: Echo! (echo echo echo echo)

Echo! (echo echo echo echo)

Echo! (echo echo echo echo)

Echo! Location!

x2

 

Glimmer: So how on earth does this work?

 

Rue: Pay attention or you'll get homework

 

Foxface: First they make a sound like this:

 

Rue and Glimmer: click click click click click click click

 

Foxface: The sound waves travels by moving from particle to

particle to particle to particle to particle to par-

 

(music stops)

 

Rue: What the heck Stella? (music starts) The sound waves bounce

off objects near

 

Glimmer: And let them know if the way is clear

 

Glimmer: They can tell by the time it takes

for the echo to reach them without a break

 

Foxface: Why don't you go take some action

watch out here comes a rarefraction.

 

Glimmer: When they are squeezed, that's compression

and when they are apart, that's rarefraction

 

Chorus: Echo! (echo echo echo echo)

Echo! (echo echo echo echo)

Echo! (echo echo echo echo)

Echo! Location!

x2

 

Glimmer: But how does this affect the world?

Well Daniel Kish he really served

 

Foxface: He really helped the blind's health

and it gave him a whole lot a wealth

 

Rue: Now they could "see" everything

and now they could do anything!

 

Foxface: So if ever you meet a blind friend

Tell them to thank Kish or it'd be the end

 

All: Sooooo um... yeah...
