In 1970, laboratory researcher Alan Holloway was working for sealant manufacturer Ralli Bondite of Waterlooville, England. Ralli Bondite was a wholly owned subsidiary of G & L Ralli Investment & Trustee Co. Ltd. Holloway inadvertently produced a product that was useless as a sealant, but pliable and semi-elastic.[citation needed] This novelty product was demonstrated by Ralli Bondite management to visiting executives from another sealant and adhesive manufacturer, as a means of wall mounting notices. There was no need for secrecy about the formula, as it was of no use for a gun-grade mastic, the main product of Ralli Bondite. Initially the potential of this material was not fully recognised, but later Bostik commenced research into the development of what they were eventually to launch as Blu-Tack. In its conceptual stage Blu-Tack was white, but was coloured blue in response to concerns received from marketing research regarding the possibility of children mistaking it for edible confectionery.[2]
