Extendibowl   (+7, -4)  [vote for, against]
Bowl that can be increased in volume by stacking rings upon it that gradually increase its diameter and height.

You are pouring a bowl of soup. You come to a point where if you pour any more the broth will spill over the edge of the bowl. You had predicted this occurance and decided to use the Extendibowl. At this point, you bring some of the Extendibowl rings out of storage and layer them on the rim of the bowl, where if they are stacked in proper order, they make a tight seal. You now pour the rest of your soup into the now extended-bowl.

\........./ <- an extension ring
\_____/ <- bowl

Too bad I saw an idea exactly like this last year.

Let me find it.

Maybe they deleted it, but I remember this idea.

Maybe you thought of it yourself, and assumed you read it here.

or you employ the BIGGER bowl technique

any potter knows how to make a bowl like this.

And dirty two bowls? Never!

Is any potter related to harry?

Having previously read your idea, I went to the mall today and there was a Tupperware store and I was amazed at the coincidence of seeing a mechanical demonstration of their new simlar (but not identical) product being automatically expanded and colapsed. The store owner said they had come out with it in May (2004). It's called FlatOut. I've linked it.

You still haven't proven to me that this idea exists in bowl form. And the vague assertion that "any potter knows how to make a bowl like this" doesn't prove it exists, its just a snyde remark. It just suggests that potters know how to make it. Just like saying any electical engineer knows how to make some simple electronic device that has just been thought up.
