Stamina Sweets

When I was a kid sweet shops had three kinds of sweets: baby sweets, usually gummy things in the shape of something else and sold loose; "proper" sweets, bars of chocolate, packets of mints, that kind of thing; and, finally, what I'll call "Big Boy" sweets. Sweets you only bought to impress your mates with how hard you were. Giant gobstoppers (so large they were actually painful to eat), things called "Red Devils" which were basically industrial-strength aniseed, and XXXtra Strong Mints, which had the power to burn their way clean through your tongue.

This takes that category of sweets a bit further. Imagine a tiny sweet - maybe like a Skittle only smaller. Instead of having a tiny "S" emblazoned on it it has the number "1". Over this is another layer, which this time has the numeral "2" on it. And so on and so on.

Thing is, each one of these layers tastes more disgusting than the one before. It could be that each is simply more minty than the last, or it could be that each one has a different, but incrementally more nasty flavour than the last (think of the fun kids would have trying to work out what the flavour actually was. "Number 3 tastes like your Mum's pants", "Number eight is spider poo", etc.)

As the kid keeps the sweet in his mouth, each successive layer slowly (all too slowly) melts away. Eventually it gets too disgusting, and has to be spat out. The number showing on the surface of the sweet indicates the layer the kid managed to get through to, and hence shows his mates how wimpy/hard he actually is.
