• A bowl is included: Hemper list a 14mm male joint flower bowl under What's Included.
• Three colours: green, blue and teal — the full set Hemper offer.

• Flower only. Not built for concentrates.

🧠 Our Verdict

Buy the That 70's Lamp XL if filtration is what you actually want from an XL bong. Most themed glass at this price publishes one percolator or none at all; this one publishes two in series, an inline feeding a lava dome, and Hemper name both. Add 5mm glass, a 10.5-inch column and a bowl in the box, and it is the most function per dollar in Hemper's XL line. The lava dome perc is also the piece of engineering that carries the theme — the bubbles are the lava. That is rare: a novelty shape where the gimmick and the function are the same component.

Quick Summary

The Hemper That 70's Lamp XL Bong is a 10.5-inch tall, 3.5-inch diameter glass water pipe styled as a lava lamp, on 5mm glass. It runs a double percolator — an inline percolator into a lava dome percolator — and ships with a 14mm male joint flower bowl. Available in green, blue and teal. Dry flower only. $119.99 at Angies Boutique in Los Angeles, against Hemper's $149.99.

Hemper That 70's Lamp XL Bong – 10.5" Double Percolator Glass Water Pipe

Themed glass usually treats the percolator as an afterthought. The shape sells the piece, the filtration is whatever fits inside, and the spec sheet says "percolator" if it says anything at all.

This one inverts that. Hemper publish the filtration in full — a double percolator, an inline percolator feeding a lava dome percolator — which is two stages in series and the most detailed perc specification they give on any piece in this range. And the lava dome is not a generic component wearing a themed name: it is the part that makes the bubbles climb the column like a lava lamp. The gimmick and the function are the same piece of glass. Built at 10.5 inches on 5mm walls with a 3.5-inch base, in green, blue or teal. Browse the rest of the range in our bongs collection.

Summary: The Hemper That 70's Lamp XL Bong is 10.5 inches on 5mm glass with a published double percolator — inline into lava dome.

⭐ Who This Product Is For / Not For

Ideal for:

• Anyone who wants real filtration from a themed piece. Two percolators in series, both named by the manufacturer.
• Buyers who want the piece to arrive usable — the 14mm male joint flower bowl is included.
• People who want height. At 10.5 inches this is one of the taller pieces in the range.
• Anyone choosing on colour — green, blue and teal are all offered.
• Collectors running the theme across formats alongside the That 70's Peak Top.

Not recommended for:

• Concentrate users. This is a flower piece.
• Tight shelves. 10.5 inches tall and 32 ounces shipped.
• Anyone who needs a stated glass type. Hemper publish a thickness but no material grade.
• Buyers who want a confirmed joint size on the bong itself — Hemper publish the bowl's fitment and not the bong's. See Known Limitations.
• Travel of any kind.

Summary: This suits flower users who want genuine filtration and height, and it does not suit concentrates or small spaces.

⚠️ Known Limitations

• Hemper publish the bowl's joint, not the bong's. The What's Included list names a "14mm Male Joint Flower Bowl" — that is the fitment of the accessory. Hemper never state the bong's own joint size or gender anywhere on the page. A 14mm male bowl implies a 14mm female joint, but implication is not specification. Measure before buying a spare slide, or ask us and we will check the piece in store.
• No material grade published. Hemper give a 5mm thickness and no glass type — the word borosilicate does not appear on this product's page at all. We are not going to state one.
• It is not the tallest piece in the range. The High Jinx Cartoon XL Bong is 11 inches against this one's 10.5, at the same $119.99.
• Hemper do not say whether the downstem is removable. They publish two percolators and stop there.
• Two percolators mean more to clean. Series filtration is more surface for residue than a single stage. Budget a longer soak than a plain tube needs.
• Flower only. The chamber and the double perc are tuned for smoke.

Summary: The trade-offs are an unpublished bong-side joint size, no material grade, and more internal surface to clean.

⚙️ Features & Benefits

• Double percolator, inline into lava dome — the headline. Two filtration stages in series, both named by Hemper. Smoke passes the inline first, then the dome, so it is broken up twice before it reaches you.
• The lava dome perc carries the theme — it is what makes the bubbles climb the column the way a lava lamp does. The novelty and the function are the same component rather than competing for space.
• 5mm glass — published thickness, at the heavier end of Hemper's range, and the reason the piece ships at 32 ounces.
• 10.5 inches of column — height is the other thing that cools smoke, and a taller piece gives the double perc more distance to work with.
• 14mm male joint flower bowl included — listed by Hemper under What's Included. Most pieces in this drop publish no bowl at all.
• Three colourways — green, blue and teal, the complete set Hemper offer.
• 3.5-inch base — a wide enough footprint to sit stable at this height.

Summary: Two named percolators in series, 5mm glass, 10.5 inches of column, and a bowl in the box.

📐 Structured Specs

Summary: 10.5 inches, 3.5 across, 5mm glass, a double percolator, and a 14mm male joint bowl included.

🔌 Compatibility & Requirements

Works with:

• The included 14mm male joint flower bowl, which is what Hemper ship with it.
• Dry flower, ground to a medium consistency.
• Water, filled to just above the lower percolator.
• Any lighter or hemp wick.

Not compatible with:

• Concentrates in practice — the chamber and double perc are tuned for smoke.
• Puffco Peak attachments. Entirely different fitment; the That 70's Peak Top is the version of this theme built for a Peak.

Before you buy a spare bowl: Hemper publish the included bowl as 14mm male, which tells you the accessory's fitment. They do not publish the bong's own joint size or gender. Rather than assume, measure it or ask us — we will check the piece in store. Spares and upgrades are in our glass bowls and slides range once the fitment is confirmed.

Summary: The included bowl is 14mm male; the bong's own joint is unpublished and worth confirming before buying spares.

🧼 How to Use & Troubleshooting

Filling and using it:

1. Fill with water until the lower percolator sits just under the surface. With two percs in series the fill level matters more than on a single-stage piece — too much and the upper stage floods.
2. Take one dry pull with no bowl seated to check the level. Water reaching the mouthpiece means you have overfilled it.
3. Seat the included 14mm bowl and pack it loosely so air still moves through both stages.
4. Light the edge of the bowl rather than the centre and draw steadily. A double perc rewards a slow, even pull.
5. Empty the water after every session. Standing water is what makes glass smell, not the smoke.

Cleaning — budget more time than usual: two percolators mean roughly twice the internal surface of a single-stage piece, and residue collects in both. Add coarse salt and isopropyl alcohol to the chamber, cap the openings, and agitate for longer than you would on a plain tube. Rinse thoroughly with warm water — trapped alcohol in a series perc affects flavour — and stand it upright to dry fully. Our guide to bongs, bubblers and glass bowls covers general glass care.

Troubleshooting:

• Problem: the draw is tight. Solution: with two percs, one blocked stage chokes the whole path. A full salt-and-alcohol soak restores airflow.
• Problem: water pulls up to the mouthpiece. Solution: overfilled. The upper perc has flooded — pour some out and retest dry.
• Problem: it gurgles heavily. Solution: too much water, or flower has fallen through into the lower chamber.
• Problem: material pulls through the bowl. Solution: grind coarser, or drop a small glass screen into the included bowl.
• Problem: flavour is off after cleaning. Solution: alcohol is trapped in one of the percs. Rinse again with warm water and dry longer.
• Problem: flavour has gone flat during use. Solution: change the water before assuming it needs a full clean.

Summary: Fill just above the lower perc, draw slowly, and give a double-perc piece a longer soak and a longer rinse.

⚖️ Comparison Table

All four cost $119.99. The High Jinx Cartoon XL is the taller piece at 11 inches, and this is second at 10.5. Where this one leads is filtration: it is the only piece in the group with two named percolators in series, and one of only two that includes a bowl. The Lucky Cat XL is the pick if you want the same price in a short, wide, stable shape instead. If you are weighing several, our guide on choosing from a premium smoke shop works through what matters.

Same theme, different job: the That 70's Peak Top at $79.99 puts the lava lamp on a Puffco Peak for concentrates.

Summary: Second tallest of the four $119.99 XLs, and the only one with two named percolators in series.

💬 Common Questions & Answers

How big is the Hemper That 70's Lamp XL Bong?
10.5 inches tall and 3.5 inches in diameter, on 5mm glass, all published by Hemper. That makes it the second tallest of the four Hemper XL bongs at $119.99 — the High Jinx Cartoon XL is 11 inches. It ships at 32 ounces.

What percolator does it have?
Two. Hemper publish a "double percolator: inline percolator to lava dome percolator", which means smoke passes through an inline stage and then a dome stage in series before it reaches you. This is the most detailed percolator specification Hemper publish on any piece in this range, and the lava dome is also what produces the climbing-bubble effect the theme is built around.

Does a bowl come with it?
Yes. Hemper list a 14mm male joint flower bowl under What's Included. That is worth noting because most pieces in this Hemper drop publish no bowl at all.

What size joint does the bong have?
Hemper do not publish it. They state the bowl is a 14mm male joint flower bowl, which is the accessory's fitment rather than the bong's. A 14mm male bowl implies a 14mm female joint on the bong, but that is an inference and we are not going to print it as a specification. Measure before ordering a spare slide, or ask us and we will check the piece in store.

What colours does it come in?
Green, blue and teal. That is the complete set Hemper offer — there are no other colourways.

How do you clean a double percolator?
Give it longer than a single-stage piece. Two percs mean roughly twice the internal surface for residue. Use coarse salt and isopropyl alcohol, cap the openings, agitate for longer than you would on a plain tube, then rinse thoroughly with warm water — trapped alcohol in a series perc affects flavour — and dry it upright and fully.

What is it made of?
Glass. Hemper publish a 5mm thickness and no material grade for this piece, so we are not going to specify one beyond what they state.

Summary: 10.5 inches on 5mm glass, a double percolator in series, a 14mm male bowl included, and three colourways.

🛒 Complete Your Setup

The bowl is in the box, so nothing is required to start. Grind consistency matters more than usual on a double-perc piece — material that pulls through has two stages to clog rather than one — and the Santa Cruz Shredder Hemp Grinder gives the even medium grind it wants. Our guide to keeping a grinder clean pairs with it.

Two percolators also mean more cleaning, and Dr. Dabber Iso-Snaps are worth keeping alongside it for quick work between full soaks. Once the bong's joint size is confirmed, spare slides are in glass bowls and slides, and the full range sits in Hemper. Everything ships from our Los Angeles shop, with same-day pickup at 838 N Broadway.

Summary: A grinder and cleaning supplies are the sensible pairings with a double-perc piece.
