NWTN Home Bolla Gravity Bong

Meet the NWTN Home Bolla Gravity Bong — a sophisticated tabletop reinterpretation of the classic homemade gravity setup. It delivers the familiar water-displacement function without involving a chopped-up bottle, an old bucket or a suspicious explanation about what happened to the kitchen scissors.

Inspired by the bold shapes and playful geometry of the Memphis design movement, the Bolla features a rounded bubble-style silhouette with a clean, vintage-influenced finish. It is part functional waterpipe bong, part modern glass sculpture and considerably more elegant than anything traditionally assembled beside a sink.

The Bolla consists of a clear outer glass shell and a removable inner glass core. As the core is raised through the water, displacement creates the airflow that fills the chamber. Lowering the core then provides a controlled gravity-assisted delivery, allowing the design to do the hard work while you admire the bubbles.

Both main components are made from thick, hand-blown borosilicate glass. This gives the piece a reassuring feel, excellent clarity and the clean flavour associated with premium borosilicate glass bongs.

A flexible silicone gasket sits between the glass components to help cushion the contact point and maintain a secure fit during use. This thoughtful little detail prevents the inner core and outer shell from meeting with quite as much enthusiasm as two unprotected pieces of glass normally would.

The Bolla includes a removable 14mm glass slide and bowl, providing a familiar and straightforward setup for legal dry herbs. The standard fitting also makes it easier to find suitable alternatives from our collection of 14mm glass bong bowls if a replacement or different style is required.

Standing approximately 8.1 inches, or 20.6cm, tall with a diameter of around 3.5 inches, or 8.9cm, the Bolla has a compact tabletop footprint. It is large enough to feel substantial but discreet enough for smaller shelves, side tables and carefully organised smoking stations.

The minimalist four-part construction also makes maintenance refreshingly simple. The glass shell, inner core, bowl and silicone gasket can be separated, allowing each section to be cleaned individually rather than forcing you to shake one complicated glass maze over the sink.

Modern, compact and beautifully unconventional, the NWTN Home Bolla is an essential addition for anyone who wants classic gravity function in a far more refined form. It is vintage-inspired smokeware for people who appreciate clever engineering, playful design and products that do not look homemade because they absolutely are not.

FAQs

How tall is the NWTN Home Bolla Gravity Bong?

The Bolla measures approximately 8.1 inches tall, which is around 20.6cm.

What is the diameter of the Bolla?

Its approximate diameter is 3.5 inches, equivalent to around 8.9cm.

What is the NWTN Home Bolla made from?

The main shell, removable core and bowl are made from borosilicate glass. A flexible silicone gasket is included to cushion the connection between the glass sections.

Is the Bolla a tabletop gravity bong?

Yes. Its compact, stable design is intended for use on a secure tabletop or other flat surface.

How does the Bolla Gravity Bong work?

Raising the inner core through the water creates displacement that draws smoke into the chamber. Lowering the core after removing the bowl provides a controlled gravity-assisted delivery.

What size bowl does the Bolla use?

It comes with a removable 14mm glass slide and bowl.

Can the included bowl be replaced?

Yes, it may be replaced with a correctly sized and compatible 14mm accessory. Always confirm the joint size and fitting before purchasing a replacement.

What does the silicone gasket do?

The silicone gasket helps cushion the glass contact point and supports a secure fit between the removable inner core and outer shell.

How many separate components does the Bolla have?

The complete set contains four main components: the outer glass shell, inner glass core, 14mm glass slide and bowl, and silicone gasket.

Is the NWTN Home Bolla discreet?

Its compact footprint and sculptural glass design make it more discreet and décor-friendly than many traditional or homemade gravity setups. It should still be stored securely when not in use.

Is borosilicate glass unbreakable?

No. Borosilicate glass offers good durability and resistance to normal temperature changes, but it can still crack or break if dropped, struck or handled carelessly.

Is the Bolla easy to clean?

Yes. Its four main components separate, allowing the glass shell, core, bowl and silicone gasket to be cleaned individually.

How should I clean the NWTN Home Bolla?

Separate all components and clean the glass sections using sea salt with at least 70% isopropyl alcohol or another suitable glass cleaner. Rinse thoroughly and allow every component to dry completely before reassembly. Wash the silicone gasket separately using a mild suitable cleaner.
