Soiloponics demo.    Use a "boar scare" to irrigate  a little greenhouse planter.

I use airlift pumps to automatically water plants in my greenhouse.  But the airlift pump just drips water in one spot and often much of the rest of the soil is dry.   The bore scare collects a few minutes worth of water,  and dumps it all at once into a pipe so that it can spread much more evenly across the planter.
