Saw this way back when I was younger on TV and was probably very influential in my becoming interested in inflation (unlike must of you, I didn't see Willy Wonka until about 10 years ago) Oh how I wish there were such a product that would have this effect.
Thanks for that. It reminds me of games i used to play as a child, before i realised what all this was about for me.
I think there's an older Laurel And Hardy where Laurel drinks lots of water and gets bloated, but i couldn't tell you any more.
