it would explode and it would hurt inside your mouth and you might possibly die so don't ever do it as a trick unless you want to die or it's fake and you want to fool somebody or people. my advise is no matter what don't do it!
That would be called a ball gag.
It explodes
Someone would be screaming in pain.
The kinetic energy would transfer Ping Pong ball!
The ball would roll downhill.
You would get Lugia.
You would fall
no
The earth would be like pluto a ball of Ice
He moves on!
Depending on your balance and where the ball is you will probably fall.
the whole world would freeze and we would die
