Background: James Watt  (30 January 1736 (19 January 1736 OS) - 25 August 1819) was a Scottish inventor, mechanical engineer, and chemist who improved on Thomas Newcomen's 1712 Newcomen steam engine with his Watt steam engine in 1781, which was fundamental to the changes brought by the Industrial Revolution in both his native Great Britain and the rest of the world. While working as an instrument maker at the University of Glasgow, Watt became interested in the technology of steam engines. He realised that contemporary engine designs wasted a great deal of energy by repeatedly cooling and reheating the cylinder. Watt introduced a design enhancement, the separate condenser, which avoided this waste of energy and radically improved the power, efficiency, and cost-effectiveness of steam engines.
Context: From an early age Watt was very interested in chemistry. In late 1786, while in Paris, he witnessed an experiment by Berthollet in which he reacted hydrochloric acid with manganese dioxide to produce chlorine. He had already found that an aqueous solution of chlorine could bleach textiles, and had published his findings, which aroused great interest among many potential rivals. When Watt returned to Britain, he began experiments along these lines with hopes of finding a commercially viable process. He discovered that a mixture of salt, manganese dioxide and sulphuric acid could produce chlorine, which Watt believed might be a cheaper method. He passed the chlorine into a weak solution of alkali, and obtained a turbid solution that appeared to have good bleaching properties. He soon communicated these results to James McGrigor, his father-in-law, who was a bleacher in Glasgow. Otherwise he tried to keep his method a secret.  With McGrigor and his wife Annie, he started to scale up the process, and in March 1788, McGrigor was able to bleach 1500 yards of cloth to his satisfaction. About this time Berthollet discovered the salt and sulphuric acid process, and published it so it became public knowledge. Many others began to experiment with improving the process, which still had many shortcomings, not the least of which was the problem of transporting the liquid product. Watt's rivals soon overtook him in developing the process, and he dropped out of the race. It was not until 1799, when Charles Tennant patented a process for producing solid bleaching powder (calcium hypochlorite) that it became a commercial success.  By 1794 Watt had been chosen by Thomas Beddoes to manufacture apparatus to produce, clean and store gases for use in the new Pneumatic Institution at Hotwells in Bristol. Watt continued to experiment with various gases for several years, but by 1797 the medical uses for the "factitious airs" had come to a dead end.
Question: did he do other experiments?
Answer: He passed the chlorine into a weak solution of alkali, and obtained a turbid solution that appeared to have good bleaching properties.

Background: Adam Mitchel Lambert (born January 29, 1982) is an American singer, songwriter and stage actor. Since 2009, he has sold over 3 million albums and 5 million singles worldwide. Lambert rose to fame in 2009 after finishing as runner-up on the eighth season of American Idol. Later that year, he released his debut album, For Your Entertainment, which debuted at number three on the U.S. Billboard 200.
Context: Lambert is best known for his theatrical performance style and meticulous attention to detail in all aspects of his personal presentation. He draws upon extensive stage experience in the ease with which he can refine and define his image through fashion and other imagery, which are essential to how he chooses to inhabit his songs, rivet his audiences and showcase his individuality. While a contestant on American Idol, Lambert's precise yet varied stagings of himself kept audiences and judges glued as much to his presentation as to his vocal talent. His signature flamboyance and glam rock styling was a break-out moment in men's fashion, duly noted by fashion publications and taste-makers, who compared him to Lady Gaga in terms of crossing style boundaries and being unabashedly individual.  Lambert made three fashion related TV appearances at the close of 2010. He fused his passion for music and fashion on MTV's "Talk@Playground", appearing in discussion with Skingraft designer Jonny Cota. He was a guest judge on Project Runway, in an episode that styled a rock band for their upcoming Rolling Stone cover. He was the subject for whom the young designers of "All on the Line with Joe Zee" created a modern look, which he then critiqued along with the show's hosts.  Lambert continued to grace the covers of magazines, moving more specifically into the fashion and culture space. Reflecting the mood and concept behind his album Trespassing, the Fault Magazine fashion shoot exemplified Lambert's commitment to aligning the elements of his artistic vision so that a cohesive narrative emerges. When Lambert appeared on the December 2012 cover of London-based high style magazine Fiasco's "Obsession" issue, he again took the opportunity to manipulate and provoke with his image and style. Sporting a sophisticated, minimalist look that recalled old Hollywood, Lambert played with male stereotypes and representations; and in the interview, emphasized that his fashion and presentation are often disparate from gay as well as straight regimes: "For the general audience, they look at the way I style myself and they go, 'Errrr, that's gay', but you ask a handful of gay guys and they're like, 'I would never wear that!'" In August, 2015, he was one of four artists to appear on the cover of Billboard's "Music's Men of Style" issue. He discussed his natural shift towards a cleaner, more classic look; and reiterated that the intersection of music and fashion--the constant motion of trends--is a fascination and part of being a pop musician.  Lambert is represented by London-based MiLK Management modelling agency as of July 2016.
