Edible toy car

This is a toy car, constructed from the rich smorgasbord of engineering materials which may be found in the average sweetshop. Tyres and other soft parts of the car are made from soft chewy sweets, The clear windows are made from transparent hard candy (e.g. in the UK, Fox's Glacier Mints) and the bodywork can be moulded from almost any hard material - toffee, chocolate, etc. The only really hard part, which I don't yet have a good solution to, is what to make the axles out of, and especially how to make them not either melt or seize in hot, humid climates.

These cars will be great for creative play. Small children can smash these cars up (and then eat them) and at the same time fulfill their normal, healthy childhood urges to recreate horrific car crashes. Chocolate versions of these cars could be melted with a magnifying glass to pretend the car is being zapped by a ghastly alien death ray.
