Picture of How to make an irrigation system.
this is an instructable on how to make a simple irrigation system out of:

paper or plastic cups whatever you choose is up to you.

straws or tubes or pipes or whatever.

a pencil.

a thumbtack or a drill if you use plastic cups.

Step 1: Poking holes.

Picture of poking holes.

Take the pencil and poke holes near the bottom of the cup so that the straw will fit in the hole snug, repeat with the other cup.

I used this with my 5th and 6th grade engineering class as an introduction to the irrigation system they will design and build. Turned out to be a really cool and quick lesson. Thanks for posting!
