Sprinkler

Hose
PVC pipe
Small nail
Drill
Drill bit
Silicon (no gaps)
Insulation tape
Hose head
And PVC pipe cap

Use small nail to make holes in your hose. I suggest three holes in the shape of a triangle at least 20 to 30 cm apart

Do the same with your PVC pipe drill three holes or more to what you desire n give a spacing of 20-30cm apart

With your hose this here will be your last step. Put the head of the hose to stop water from coming out and the other end to the tap ready to use

Connect your PVC to a metal PVC and then to flexi hose witch is then connected to a hose also put a PVC cap at the end of the PVC pipe. All of these are connected using silicon no gap and insulation tape, make sure the silicon drys before you use the sprinkler. Now connect the hose to the tap ready to use

Turn the tap on and use it
