I'm talking about that video that thing looks killer. Are we allowed to see how it works?
That one was inspired by the open airflow of the Showerhead which was one of my favorites, but I added an improvement to promote more turbulent mixing.
It sits directly onto 19mm male glass adapters for easy sourcing of bowls.
You can either run it with a basket screen in the bowl for small dose hybrid heating, or with a screen further down at the bottom of the male joint for nearly pure convection and larger amounts. It's pretty versatile!
I sent one to Vgoodiez who made a vid on it. I actually sent him a message the other day wondering if he's still using it, but I haven't seen him around in a while. I never made a thread on it though so it didn't get posted here on FC. InV2 is different but uses concepts learned from that project. I ended up not really loving the male joint as a bowl.
