Got to love a viral video right?  I'm sure this woman wasn't thinking how funny in the moment!

It happened at the International Spy Museum Washington, D.C., when a shark tank exhibit was found.  But there were no actual sharks. It’s just a hyper realistic screen.  You tap on the glass and then a ‘shark’ comes out of nowhere and attacks! The woman was so frightened and shocked by the shark she fell back.

As a practical joke, who could you see doing this too?
