It's one of life's great mysteries - what actually goes on inside a dishwasher?
Turns out it's a lot less magical and slightly more phallic than you imagined.
Although it was filmed a year ago, the clip has recently exploded online being viewed over 1.5 million times.
The person behind it, Bito, said: "Always wanted to see what happens in my dishwasher after I close the door. Many of the other videos I saw had terrible lighting or bad angles.
"Using a Hero 3. I had two light sources reflecting at different angles.
"This was my third attempt. The biggest problem I had to overcome was the heat and battery time."
Good work Bito, good work...
