Imagine stepping into a chemistry lab and replacing that scribbled calculation on a piece of paper with the press of a button. That’s exactly the promise of the Moltimeter, a clever gadget dreamed up by a 17-year-old from Le Pecq. In a world where precision matters and every second counts, this invention could transform routine lab work into a seamless experience.
a young inventor’s journey destined for greatness
In the quiet suburb of Le Pecq, just north west of Paris, 17-year-old Thibault de Percin was never without a scrap of paper and a pair of scissors. “He spent his weekends constructing cardboard vehicles that somehow actually moved,” recalls his mother, Caroline. From the moment he could read, Thibault was engrossed in science magazines, eagerly devouring every issue of Sciences et Vie Junior. It was there he first heard of Innovez!, the competition run by the Musée des Arts et Métiers to spotlight budding innovators.

Having honed his knack for innovation over years of makeshift workshop experiments at home, Thibault made the shortlist of just twelve finalists. On 3 March, he will present his invention in the grand hall of the Arts et Métiers museum, vying for a €1,200 prize and, more importantly, the chance to show professional chemists how a teenager’s spark of curiosity can solve a routine problem.
the Moltimeter a clever answer to a classroom puzzle
Anyone who’s sat through a chemistry lesson knows the drill: weigh out a sample in grams, then manually convert to moles using formulas or a spreadsheet. It is a task as repetitive as it is error-prone. One afternoon, after yet another scribble-filled exercise, Thibault asked his teacher if there was a device to automate the process. When the answer was no, he decided that perhaps there should be.
The result is the Moltimeter, a compact unit that pairs a precision balance with a microprocessor programmed to calculate moles at the touch of a button. Place your sample on the tray, enter the molar mass, and the device displays the exact mole count. “Accurate mole measurements are the bedrock of stoichiometry,” notes the Royal Society of Chemistry, highlighting how a simple gadget can streamline laboratory work. “Automation in routine calculations can significantly reduce human error in laboratory settings,” adds the American Chemical Society.
While not a world shaking breakthrough, the Moltimeter promises to rescue students and seasoned researchers alike from hours of tedious number-crunching. As Thibault observes, “If we can reclaim a few minutes every time we do an experiment, that time really adds up.” Should the device ever reach commercial production, it might soon find its place alongside pipettes and test tubes in schools and research labs around the globe.
Whether the Moltimeter goes on to reshape everyday chemistry or remains a clever student project, one thing is clear: innovation often begins with a simple question asked at just the right moment.
