Astro Snack. Black Holes.
 
[MUSIC]
 
Like this ball of rice, black holes form after matter is smashed by gravity into a tight space.
 
[WHIMSICAL MUSIC]
 
(DESCRIPTION)
Wooden hammers smash a cartoon ball of rice.
 
(SPEECH)
Hi! I'm Mochi!
 
Once a black hole has formed--
 
Wow!
 
It has the same mass it had before.
 
So small!
 
But in a much, much smaller space. When dust, particles, and light flow nearer and nearer to a black hole, they can become trapped-- forever.
 
(DESCRIPTION)
Particles fall onto the ball of rice.
 
(SPEECH)
More dust, please!
 
[STATIC]
 
Not even light can escape.
 
I'm fine!
 
I'm fine too!
 
But don't worry. Objects have to be very, very close to fall into a black hole.
 
(DESCRIPTION)
A long, wiggly string is sucked into the black hole.
 
(SPEECH)
[MUSIC]
 
(DESCRIPTION)
The black hole recedes. Astronaut avocado slides past.
