I need a volunteer!
You right here in the corner. Is it water?
Put your hands in it.  Make sure it's water,
don't trust me.
water? Keep going deeper.
Grab a few.
Show the audience.
There was actually things in the water,
little crystals. What happened there is,
there are actually some materials out there
Thank you very much grab a couple
napkins,
round of applause please. So what happened
with those little crystals is actually
the light when it goes through it,
it doesn't bend at all. So it behaved just
like water so we don't see it at all so
we can hide things
when you wanna hide things from your
parents. That's what you're gonna use.
