Einstein, Newton and Pascal decide to play hide and seek.

It's Einstein's turn. He counts till ten and opens up his eyes.

Pascal is nowhere to be seen.

Newton is sitting right in front of Einstein with a chalk in his hand. He's sitting on a box he's drawn, one metre a side.

Einstein: Newton you're terrible, I can see you!

Newton: No No Einy, you've found one Newton per square metre. You've found Pascal!
