Water Geyser
From ATLauncher Wiki
Water Geysers are a block introduced by Mariculture. By putting them on a tank containing water, using water buckets or pipes, the water geyser will activate. The geyser has quite a long range
If you put pressurised water in them, they have a larger range.
It can be placed without any supporting structure. Using a crescent hammer will allow you to rotate the geyser. It can send a stream along any axis.
Touching the water stream will propel you fast along its current, essentially showing use as a mob pusher. You can essentially stand on top of the geyser stream when its placed vertically.
