Curious Aseem

Aseem was a good little boy and always very curious.
Every day he peed and pooped in the potty and flushed after he was done & his bottom wiped.
One day he wondered, what happens when I flush?
So he asked his Mommy. She said let's look.
So they opened the lid of the toilet tank and saw the tank full of water.
Then Aseem pulled the flush lever down.
The cover at the bottom got pulled up.
With a big WHOOOOSH the whole tank emptied into the toilet, carrying away the poop.
Just as the tank became empty, the cover at the bottom sank down and covered up the hole.
Then fresh water came gushing through a hole near the top and started filling up the tank once again.
The toilet was ready to be used again.
Aseem was satisfied.
