A trip to the aquarium is usely a leisurely experience, but one woman got the shock of her life when she visited one in Washington.
A video has surfaced of a grandmother in the ultimate under-the-sea prank, as she's convinced she's about to be attacked by a terrifying shark.
The clip, originally from 2014, but now doing the rounds again on viral forums including Reddit, shows the lady nearing towards the glass tank at the International Spy Museum in Washington, D.C.
Others around her encourage her to get closer and give the glass a little harmless tap, but just as she touches it, the shark makes a fierce turn towards her, showing its teeth and seemingly smashing the glass.
Unsurprisingly, the terrified woman jumps back and squeals, at this stage not knowing it's all a prank.
It was actually a pre-recorded video that she was being shown of a shark, all a part of the museum's 'Exquisitely Evil: 50 Years of Bond Villains' exhibit.
