This is a Comedy trope that can be seen very often in Western Animation. A character comes across a geyser and becomes innately curious about it as he looks directly into it, when the geyser suddenly erupts in a torrent of water that thrusts the character up into the air. This sometimes results in the victim bouncing around on the top of the spray.
This is not Truth in Television, because a person will just get thrown back a few feet from such high water pressure. And be cooked by the superheated water.
This is often a mechanic in video games (usually of the Platformer genre), and the geysers end up being moving and/or slippery platforms.
Can go hand-in-hand with: Making a Splash
- This trope is taken Up to Eleven in One Piece during the Jaya Arc: The quickest way to reach the White Sea and the Sky Island is to use the Knock Up Stream, a colossal water jet which can propel ships into the sky (though in most cases they're turned into wrecks). To top it off, is later revealed that the "land" on Skypiea was actually half of the Jaya Island propelled into the sky by a really gigantic Knock Up Stream.
- In The Goonies, this happens to Troy while he is in the bathroom, and Mikey and the others were fooling around with the water pipes. However, this would also count as a Special Effect Failure, because while Troy is thrust up into the air by the water from the toilet, you can clearly see the platform on which he is sitting that makes the stunt work.
- John McClane is shot out of a sewer pipe 10 feet into the air in Die Hard with a Vengeance.
- Subverted with the 1939 The Three Stooges short "Oily to Bed, Oily to Rise" in that this trope happens with oil instead of water. While the Stooges are cleaning out the water pump belonging to a kindly old lady, oil spurts out from the pipe. Curly sits on the pipe to plug it up but is propelled into the air by the oil geyser a few seconds later. This gag was reused in a later short, "Oil's Well That Ends Well", in which Joe Besser stops up the oil gush instead. As footage from the former short was used here, careful observation will reveal that it's Curly on the oil geyser and not Joe.
- A clip used in The Hollywood Clowns showed a guy being sent skyward by a suddenly broken fire hydrant.
- Hogfather: This happens to Archchancellor Ridcully when he tries out the bathroom built by B.S. Johnson. Bonus points for Ridcully remarking afterward, "Ye gods, I feel so clean."

- At the end of the Bugs Bunny short "Oily Hare", an oil tycoon and his flunky who had been chasing after Bugs throughout the cartoon both get thrust up into the air on a carrot geyser that had been caused by a ludicrous amount of dynamite that had been shoved into Bugs's rabbit hole, in an attempt to get him out.
- In "Frigid Hare", the villain is carried away bouncing on top of a whale's spout.
