Your brain was bitten by a dog

In truth, this little magic trick was very simple. Ye Wanwan plucked off a pearl button from her clothes earlier and placed the pearl on her right ear when Big Dipper and Seven Star weren't paying attention.

When the cup slammed down onto the desk, the pearl button coincidentally dropped into the cup, so the trick was all inertia and physics.

Big Dipper and Seven Star's attention was focused on her hand and cup, so they didn't notice her right ear.

"D*mn… Sis Feng… Your hand was kissed by an angel, right… So awesome!" Big Dipper exclaimed as he picked up Ye Wanwan's right hand.

"Let me try!" Big Dipper immediately picked up the cup and firmly slammed it onto the desk.

The cup was then shattered into pieces with a "Bang."
