London UK-based Mathmos is getting set to release their new Fireflow lava lamps. The lights eliminate the need for electricity, instead substituting the heat of a simple tea light candle.

The Fireflow R1 and Fireflow O1 were designed by the same company that invented the original lava lamp over 45 years ago. The R1 looks like a tiny rocket ship, loaded up with bubbly goo that gradually morphs under the warm glow of candlelight.

The O1 features a modern design that floats a mouth-blown glass lava container several inches in the air above the flame.

Both versions are is available in a variety of fluorescent colors, as well as a sparkly glitter version, sans lava. You can also choose from a chrome or black metal finish. Burn time is rated at appx. 3 hours – or however long an average tea light glows.

Mathmos expects to ship the Fireflow lava lamps this Fall, with the Fireflow R1 selling for £29 (appx. $49 USD), and the Fireflow O1 priced at £35 (appx. $60 USD).

These tiny Light Charms clip onto your mobile phone and blink whenever a call is coming in (thanks to those lovely radio frequency emissions.) They’re available in both a mini light bulb version (in white or blue) and a mini lava lamp version (in red or blue) which is only appropriate since Mathmos was the original creator of the lava lamp back in the sixties.

They’re just £6 each (about $12 USD) from Mathmos’ U.K. online store.
