What are the sprinklers that are underground that pop up a circle on the top and they go tic tic tic like a regular sprinkler?
You could be referring to the underground Gardena sprinkler system that has a rotary head which pops up in a circle. They magically pop-up when it is time to water your garden. Check out a picture of this system at http://www.gardena.com/int/water-management/sprinkler-systems/.
That is a built in sprinkler system
