Because I'm housebound most of my ideas have to do with house and garden. Boring for you but fun for me.
I think this is the third one I've fed in about teeth for example - along with 80-"odd" other 'Bakers similarly obsessed by matters dental.
This idea is for a new kind of toothpaste tube
with siamesed vertical compartments - 2,3,4 or even more.
One could make a prototype by taping some fat crayons together. Got it? Manufacturing machinery would form by buckle-and-weld two sheets together.
Each minitube would have its own screw-cap.
What fun marketeers could have deciding on a brand-name to start with, such as Cxlgxtx Multitubes, or MiniTubes, or TripleTubes, or QuadriTubes? or TubeTubes ... whatever.
Then would come the problem of what to put IN the MultiTubes.
Paste with differing flavours? Differing colours? Differing functions? Like #1 whitens. #2 brightens. #3 frightens [makes you hate the taste of tobacco products].
Or "a ColourPaste MixnMatch MultiTube gives you the chance you've always wanted - the opportunity to colour your teeth to match your hsir" ... but I'd better stop.
I've already over-run two separate postings.
