Beakman's World
Toilets and Gravity
Beakman explains who made the toilet and then shows a cross-section of a toilet to show the inside. Then he uses colored water to show how gravity pushes the waste out of the toilet into the drain. He then shows how the back tank of the toilet works with valves and gravity to push the water in the toilet bowl down into the drain.

so what's the story
0:04
just the bathroom bomb site go boom
0:08
and you time Lester
0:11
the reason I'm so stoked about the toilet
0:14
it's because everything about it is so full of
0:19
science
0:21
there's more pressure
0:23
air pressure
0:24
levers
0:25
gravity
0:26
but first
0:27
some background
0:29
background I got annoyed right now about the Big Bang in the bathroom
0:33
this man's name was Thomas [censored]
0:37
yes
0:38
was his real name
0:41
in 1884 he unveiled
0:43
a remarkable new version of the toilet called crappers valveless Water waste preventer
0:51
age of modern plumbing
0:53
had begun
0:55
can we move this along
0:58
I know I know the suspense is killing you
1:00
it isn't exactly suspense
1:03
let's start
1:03
our toilet tour
1:05
here
1:06
with the boss
1:07
the Super Bowl
1:08
boy
1:12
let's say this blue food coloring is human
1:16
waste
1:18
what happens
1:19
when you flush the toilet is
1:22
this
1:23
a measured amount of water pours into the bowl
1:26
which horses the stuff already in the bowl
1:28
down through this pipe
1:30
and into the sewer down here
1:33
salt
1:34
here we go
1:36
I put the waste in the toilet
1:40
blushing
1:46
see how the water from the bucket
1:48
horses the colored water to go out the bottom
1:52
then it's up and over this Bend
1:54
and down this pipe
1:56
where it eventually connect with the sewer
1:59
and
1:59
when it's all done
2:01
the colored water has gone down the drain
2:05
and the water in the bowl is clean and clear
2:08
but even though the water looks clean and clear
2:12
don't ever put your hand in the toilet
2:15
by the way
2:16
all the water never empties out of the toilet
2:20
fact
2:21
in your lifetime you'll use over a million gallons of water
2:25
just to flush the bathroom Barcalounger
2:28
just tell me
2:30
do they or don't they
2:34
keep your pants on will ya
2:38
since most people
2:38
but wouldn't like the idea of keeping a bucket of water around for every time they want to flush the toilet
2:45
we have
2:47
the tank
2:48
yes
2:49
the job of the tank is to be sort of a salt refilling flush bucket
2:54
it holds enough water
2:57
to force the water in the bowl
2:59
down
3:00
the pipe
3:02
when we flush
3:03
the handle right here
3:05
which is part of a lever
3:07
pulls up on this
3:08
chain
3:09
which lifts
3:10
this thingy
3:11
called a flapper valve
3:13
the flapper valve uncovers a hole in the bottom of the tank
3:17
sort of like turning the bucket upside down
3:20
and the water drains glug glug glug
3:23
glug
3:24
out of the tank and into
3:26
the bowl
3:27
where it doesn't blow up
3:31
that's for me to know and for you to find out
3:35
here's what it looks like
3:41
thank you Ray-Ray
3:44
he's in the toilet
3:46
all right
3:48
here we go
3:51
while the water level in the tank is going down
3:54
gravity is pulling down this float at the end of this long metal rod
3:59
that opens this valve
4:01
which lets more water in
4:04
meanwhile back at the flapper valve
4:06
as soon as all the water is out of it
4:08
tank
4:09
it seals off the hole so the tank can fill up and be all ready for the next flush
4:15
just tell me
4:16
is the
