Love 'em or loathe 'em, lava lamps have seen a real resurgence in the past decade. So much so that they've had iPod docks embedded in them and even used as the starting point for over-designed speakers.
In any case, it's reassuring to know that British lighting firm Mathmos has gone back to basics with a brace of new designs that flip the bird to flipping the electricity switch and use tea lights — yes, those things you buy from IKEA in bags of a squillion because there's nothing else in the store that appeals to you — to heat up the lava. One tea lamp will give you three hours' worth of languid Barbapapa bubbles. Rad.
The Fireflow lamps will be available this Fall in four neon colors as well as a glittery version. The O1 model will cost around $60, while the R1 will set you back just under $50.
