So a lot of you who have purchased the Nammor hoses know that they have a pretty bad plastic taste when you use them for the first time. I just bought a new set and didn't want to deal with this, so I came up with a simple way to air them out so that the first smoke tastes like shisha and not plastic.
Basically, all you have to do is hang them from your ceiling and have a fan blow air through them for a few hours (I'd say at least 5 to be safe). I used a couple of funnels in order to capture more of the airflow from the fan and send it through the hoses.
Here's a crappy iPhone picture of how I set it up:
P.S.: This would probably also work well for drying the hoses after they've been washed.
