Jason Silva from 'Brain Games' stops by to play a few games with Rach and Malcolm-Jamal Warner, and you might be surprised by their skills at one in particular!

Jason did a test that he says people usually fail on his show. He tested Malcolm-Jamal and Rachael’s startle reflex by popping balloons, shooting wire snakes out of a can, and opening a jack in the box. Watch above to see their surprising reactions!

He also played a brain trick on Rachael involving blindfolding her and having her drink several glasses of milk – watch below to see the result!
