Rob's DIY Venturi http://www.youtube.com/watch?v=0ZMjDgM3LaU

I recently watched Rob Bob's (bnbob01) DIY venturi video and it looked like so much fun I thought I'd try my hand at making a small version out of easy to find local parts. I hope to be able to use this in future DWC or recirculating hydroponics experiments.

I think it would be very useful in small hydroponics, aquaponics or aquarium applications for water oxygenation.

Thanks for watching!
