Trivia time. I saw this posting and the brand name "Mathmos". I suspected what the source of the name was, having seen a certain movie about 50 years ago. Yes, their company is named for the bubbling creature living under the city in the movie "Barbarella" starring Jane Fonda. There was another noteworthy name to come out of this film: the scientist whom Barbarella was trying to find was named Durand Durand. Duran Duran the band named themselves after that character, albeit dropping the ending "d". The movie is definitely not high class, but it's amusing and some of the music is good.
