Abysmal Vapor
Supersniffer 2000 - robot fart detection device
I imagine aluminum would scratch easy from boro balls,maybe even some chips/shavings . I would be careful when getting them in/out and try to immobilize them,so they dont bounce when you hit and carry it around .It was only a matter of time before I tried this.
I'll have to double check how many are in there as it's more than you can see in the photo. I just cleaned the stem but when I had originally loaded it, the balls weren't as far up in the stem so I had to make sure they didn't block the ceramic bowl if they fell down between removing bowls. Cleaning was a breeze, I placed it in an ISO bath for a day or two and then ran ran hot tap water through the stem while covering enough of the bowl hole so the balls didn't push out from the water pressure.
There's a little more draw restriction than normal but cooling has increased as well.
Another thought ,has anyone tried to fit a glass cup inside the plastic ? Maybe they could make an insert with a some oring adapter, it would provide extra insulation from heat from hot drinks ).(thermos effect ?!)
