So I'm giving a speech on growing hydroponically...

In speech class. A demonstrative speech. Best part? I'm in my late thirties,the oldest guy in the class, and really don't look "the part".
Anyway, besides a spare air pump and stone, a clear glass with blue dyed water, what else can you guys think of for a visual aid?

1. pH/ppm meter

2. r.o. unit

3. rockwool cubes (or whatever your medium is)

4. A good hydro book

5. an LED light (or something small as an example)

6. fertilizer examples i.e. grow/flower/cal-mag/etc.


And a bowl for everyone to enjoy.
 
Hydroton, net pot, think I'm going to use yarn hanging out of it to simulate the roots. I use Jack's hydro so I might make the water blue with that. Wish I did have a tomato plant to show though.
