The Screwball Full Hybrid Bowl is the updated bowl for the Screwball by Vapvana. The Hybrid part of the name refers to the construction of the bowl which has a Grade 2 Titanium chamber section and a replaceable glass joint. The glass joints provide a quality of life upgrade as they don't expand when the bowl is heat soaked, getting stuck into the glass bubbler briefly when hot. They also allow for different size bubbler joints to be used without the need for a secondary adapter since the joints are available in multiple sizes!

WARNING: Bowls are made for Vapvana products only. Use with other heaters at your own risk.
Please note
The joints on these bowls can be quite stiff to remove. We've found the best way is to grip the glass joint and bowl firmly then pull steadily apart, don't wiggle or twist. Once it's apart you can add a little o-ring lubricant, Flower Mill wax, Dynawax or similar to the o-rings to make it easier the next time. If you're really having trouble you can use thermal expansion to assist; place your Thermal or Ruby Twist housing onto the bowl for around 15 seconds to heat it up, then hold the Titanium part with an oven glove or towel and pull the glass joint out as described here.
