‘Nostalgic and calming’: lava lamps are groovy again as sales glow
Depending on your age, you may remember them from Doctor Who and The Prisoner in the 1960s, or from TFI Friday and the Big Breakfast in the 90s.Or if you’re young enough, you might not remember them at all.But now it seems lava lamps are back.Rising sales would suggest a third wave of the lava lamp phenomenon is on the horizon, thanks to the ongoing trend towards mid-century interiors and gen Z’s fascination with the late 90s and early 2000s.Cressida Granger, the managing director of the British lava lamp pioneers Mathmos, said there had been a surge in interest in its lamps.
“It feels like they’re in the current conversation in a way they haven’t been.”Sales have been rising steadily in recent years and 2025 is set to be a huge festive season.Mathmos has oversold in the run-up to Christmas, which means the company will be short of stock come January.So what does Granger put this appeal down to? “They’re sort of nostalgic, aren’t they? So that’s comforting when the world’s changing,” she said.“They are just very calming, they’re very analogue.
They take two hours to warm up.They don’t demand anything of you, they’re very soothing.People use them for mindfulness and focus.“[In the case of Mathmos], people really like that we’re the real thing and they’ve always been made here and we invented them.So that feels also secure and authentic, and we really work hard to make them the best.
”Mathmos was founded in 1963, by the inventor of the lava lamp, Edward Craven Walker,Walker was an eccentric, a nudist who was married four times before his death at the age of 82 in 2000,He was responsible for the early success of the company, which was then called Crestworth, with his wife Christine, but when sales collapsed in the 1980s, his successor Granger oversaw the renaissance,Formerly a vintage dealer, Granger initially approached Walker to buy the formula but ended up taking over the business in 1989,Though much about Mathmos has changed, the secret recipe is still loosely based on Walker’s designs and the bottles are still filled by hand.
The factory, at Poole in Dorset, bears all the quirks expected of somewhere making such an unusual product.Upstairs, customer service staff speak multiple languages to engage with customers from its 10 international websites.Downstairs, a mesmerising showroom of lava lamps of different colours and designs enraptures anyone who enters.Adjacent to that is where the magic happens, where the bottles are filled and the lava lamps are assembled – sometimes even personalised – and boxed, ready to be shipped in time for Christmas.The original model, the Astro with the classic lava lamp shape, is still the bestseller but others such as the rocket-shaped 90s Telstar are popular, and a number of newer models including ones lit by candles have also proved a success.
“I suppose it is unusual to have a job that no one else really has in Europe,” says Alan Staton, the only person outside China who spends his working day putting the lava into the lamps.The “lava” is essentially a type of brightly coloured wax suspended in water, which is heated by a bulb and rises to the top, falling again when it cools, creating its characteristic hypnotic effect.Customers who bought a Mathmos lamp anytime in the last 30 years will have a product that was filled by Staton.His younger colleague Henry Currer has only worked at the factory for a few months – “I’m getting my head round it I think!” – having come from running a bronze casting factory in Birmingham.“What enticed me to it is that it’s a British heritage brand, something that’s made here,” he says.
“Every other lava lamp’s made in China,” says Granger.There have been periods where innovative products were copied which devastated sales, and the small company did not have the funds for legal action.But Granger has a philosophical view: “If you’re not being copied you’re not doing anything successful.“We did a silicon ball that squeezed on and off, called Bubble, that got copied by Target in America.You can’t do a lot against Target.
“But actually I spent a long time looking for the new lava lamp,” she says, “before I realised that the new lava lamp was the lava lamp,”The company has collaborated with various designers and artists, including the photographer Rankin, the band Duran Duran and the dutch designer Sabine Marcelis,Every one of these has sold out within hours, including most recently a limited edition red Rolling Stones collaboration, for which only 1,000 were made, which led to a huge queue at the band’s Carnaby Street store on the day it was released in November,“They were going for more money than people bought them for during the time we were selling them,” says Granger,Perhaps surprisingly, Mathmos’s customers are not one-offs.
“They’ve often got more than one and they often gift them.We’ve got quite a big collecting community and they’re quite active.We do have some collectors who’ve got hundreds.”She says: “It’s like a vinyl record, you have to take it out of its sleeve and there’s a ceremony to it, which is kind of nice.”
VIP viewing: cinemas bet on luxury bars and beds to usher in a new film era
From champagne coolers to front row VIP beds, cinema owners are investing heavily in premium experiences as the industry gets its box office mojo back.As the third instalment in James Cameron’s blockbuster Avatar series pulls in the Christmas holiday crowds, the UK box office is expected to surpass £1bn in 2025 for the first time since before the global Covid pandemic.Amid financially testing times – with the pace of a hoped-for box office recovery derailed by the Hollywood actors’ and writers’ strikes – cinema owners have focused on reinventing the movie-going experience to win back film fans.“We are rolling out 200 of our Ultra Lux seats, which have a built-in champagne or wine cooler, each day across Europe,” says Tim Richards, chief executive and founder of the Vue cinema chain. “Our ‘worst’ seat in the house is a leather recliner, and it is amazingly comfortable
Sustainable aviation fuel take-up in UK unlikely to hit 2025 target, data suggests
The take-up of sustainable aviation fuels is on course to fall short of the UK government’s first annual mandate, official figures suggest.Production data published by the Department for Transport (DfT) covering most of 2025 shows that sustainable fuels (SAF) only accounted for 1.6% of fuel supplied for UK flights – 20% less fuel in volume than the 2% needed to fulfil the requirement.The government introduced the mandate in January, which requires suppliers to hit targets for SAF – which the industry has argued is important for cutting its carbon emissions – within the overall UK aviation fuel mix.Themandatory target rises sharply from 2% in 2025 to 10% in 2030 and then to 22% in 2040, including the use of second-generation fuels that are seen as more sustainable in the long term
‘Undermines free speech’: Labour MP hits back at US government over visa ban on UK campaigners
A senior Labour MP has accused the Trump administration of undermining free speech after Marco Rubio, the US secretary of state, announced sanctions against two British anti-disinformation campaigners.Chi Onwurah, the chair of parliament’s technology select committee, criticised the US government hours after it announced “visa-related” sanctions against five Europeans, including Imran Ahmed and Clare Melford.Ahmed leads the Center for Countering Digital Hate (CCDH), while Melford is chief executive of the Global Disinformation Index (GDI), both of which have clashed directly with Elon Musk, the owner of X and a former adviser to the US president.Onwurah said on Wednesday: “Banning people because you disagree with what they say undermines the free speech the administration claims to seek.“We desperately need a wide ranging debate on whether and how social media should be regulated in the interests of the people
Visa ban for European critics of online harm is first shot in US free speech war
For Maga politicians, European tech regulation hits hard in two areas: at the economic interests of Silicon Valley and at their view of free speech.The action against five Europeans who are taking on harmful content and the platforms that host it has had an inevitable feel to it, given the increasingly vociferous reactions to the EU’s Digital Services Act (DSA) and the UK’s Online Safety Act (OSA). Both pieces of legislation require social media firms to protect users or face the threat of sizeable fines. Indeed, Elon Musk’s X has been fined €120m (£105m) this month for breaching the DSA.These acts are prime examples of what US Republicans see as an anti-free speech culture on the other side of the Atlantic
Hou Yifan, women’s world No 1, stars in rare appearance at Global Chess League
Hou Yifan, the all-time No 2 woman grandmaster after the retired Judit Polgar and currently ranked women’s world No 1, showed that she retained her brilliant skills when she made a rare appearance in the Global Chess League for Alpine SG Pipers, who defeated the reigning league champions, Triveni Continental Kings, 8.5-3.5 in the 2025 final at Mumbai on Tuesday. The Global Chess League, now in its third season, is planned as the chess equivalent of cricket’s Indian Premier League.The final qualifying match, in which Alpine barely secured the six game points needed to edge their opponents, proved a triumph for Hou, who studied at Oxford and is semi-retired from chess in favour of a professorship at Peking University
I was there: Carlos Alcaraz’s comeback in French Open final is still hard to comprehend
It was not until what appeared to be the dying moments of the French Open final between Jannik Sinner and Carlos Alcaraz that I realised it could be worth taking a photo of such a monumental occasion. This was, after all, the first grand slam final between the two players who seemed set to lead men’s tennis for many years to come.For three hours and 43 minutes Sinner had dominated Alcaraz and he earned three championship points while leading 5-3 in set four. Just before the Italian’s second championship point, I thrust up my phone and took a quick photo before my hand returned to my laptop, ready to file immediately an article that hailed his third consecutive major title and first triumph in Paris.Instead, it would take another hour and 46 minutes for a winner to be decided on Court Philippe-Chatrier in June
