Thinking Putty is a tradename for a Silly Putty clone (it’s actually all Dow Corning 3179 Dilatent Compound). The Thinking Putty people are bulk retailers, dealing in imposing globs of the pink stuff rather than Binney and Smith’s anemic little tablespoon-sized eggs. Their puttyworld site has some amazing video of cool putty tricks, including firing putty out of a cannon! (Cement mixer, putty putty) Link Discuss (Thanks, Elizabeth!)
