Watch: ‘Shark’ charges at man, cracks aquarium glass

One should pay attention to a sign when it says "touch at your own risk", as it can save you from some unimaginable encounters in your life.

A man in Washington DC, unfortunately, came across a similar situation decided to overlook the red warning sign hanging on a ‘shark tank’ at the International Spy Museum and banged on the 'aquarium' glass, hoping to see what would happen.

The shark exhibit at the museum is a well-known prank, where a fake shark seems to ferociously charge at the person touching the aquarium, cracking the glass. 

It has fooled many before this, but none has matched the hilarious reaction as that of Gregory Heinzman, whose video has gone viral with millions of views leaving the audience into splits.
