Take normal rope - say 1cm thick stuff. Dye it black. Sell it as "ninja rope". You could also sell "ninja poles" and I have no idea what you could call "ninja washing pegs" but I think you see where this is headed.
I am just trying to work out how to market "Ninja washing powder". "Washes blacker than black" perhaps....
And cheap to produce too! Just market paint powder. You're getting the hang of this! --Vitenka
Maybe, but only if I don't end up dangling from the end of the NinjaRope ^_^
