{"product_id":"grav-gravitron-gravity-bong","title":"GRAV Gravitron Gravity Bong","description":"\u003cp\u003eThe GRAV Gravitron is the world's first all-glass gravity smoking system, built from borosilicate glass with an upgraded V2 design featuring 5x more glass thickness and a platinum-cured silicone grommet for a tighter seal. Available in four sizes — Medium, Large, Monarch, and the limited-edition Breathe Again collaboration — it's one of the most efficient \u003ca href=\"https:\/\/vgear.com\/collections\/pipes-chillums\"\u003epipes\u003c\/a\u003e on the market with virtually no smoke lost in the process.\u003c\/p\u003e\n\n\u003cp\u003eOperation is straightforward: fill the base halfway with water, pack the bowl with dry herb, light it while lifting the bottle, then remove the bowl and inhale as you slowly lower it back. The gravity and water pressure do the work, delivering a dense, pressurized hit that would take significantly more material to achieve through conventional smoking.\u003c\/p\u003e\n\n\u003ch2\u003eFAQs\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHow does the Gravitron work?\u003c\/strong\u003e Fill the base with water, pack the bowl, light it while lifting the bottle slowly, then remove the bowl and inhale as you lower the bottle back into the water.

The result is a dense, concentrated hit with very little material needed.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBorosilicate glass:\u003c\/strong\u003e The same glass used in laboratory equipment. It handles heat better than standard glass and is far less likely to crack from thermal shock during use or cleaning.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround joints:\u003c\/strong\u003e The bowl connects to the Gravitron via a standard-size ground joint — a precise glass-to-glass fit. Any compatible male bowl in the matching size (14mm or 19mm) will work.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEfficiency and dose:\u003c\/strong\u003e The Gravitron is considered one of the most efficient smoking devices because the pressurized delivery captures nearly all smoke in the chamber before inhalation. Less material goes further.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChoosing a size:\u003c\/strong\u003e The Medium (9\") is portable and solo-friendly. The Large (11\") produces bigger hits and is better for groups. The Monarch (12\") maximizes chamber volume for the largest sessions.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecs\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e GRAV\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Borosilicate glass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSizes:\u003c\/strong\u003e Medium 9\" \/ Large 11\" \/ Monarch 12\" \/ Breathe Again 11\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJoint size:\u003c\/strong\u003e 14mm (Medium, Monarch) \/ 19mm (Large, Breathe Again)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes:\u003c\/strong\u003e Matching funnel bowl + platinum-cured silicone grommet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGlass version:\u003c\/strong\u003e V2 (5x thicker than original)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Dry herb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e GRAV (USA brand)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GRAV","offers":[{"title":"Medium","offer_id":49783377363181,"sku":"GRAV-GRAVITRON-MED","price":79.99,"currency_code":"USD","in_stock":true},{"title":"Large","offer_id":49783378215149,"sku":"GRAV-GRAVITRON-LAR","price":99.99,"currency_code":"USD","in_stock":true},{"title":"Monarch","offer_id":49783378247917,"sku":"GRAV-WP-GRVTRN-MNRCH","price":149.99,"currency_code":"USD","in_stock":true},{"title":"Breathe Again","offer_id":49783378280685,"sku":"GRAV-WP-GRVTRN-BRTHAGN","price":124.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0731\/6144\/1517\/files\/grav-gravitron-gravity-bong.png?v=1776191039","url":"https:\/\/vgear.com\/products\/grav-gravitron-gravity-bong","provider":"VGEAR","version":"1.0","type":"link"}
