Re: Light the fire
When we were kids you could make go-cart from scrap. You could go to a hardware store and buy the bits to make a go-cart too. Recently i was trying to make something using some of my experience in go-cart building and discovered the only way to buy the bits to make a go-cart was to actually buy a go-cart.
Given one of the uses was to mount a Ram Jet kickstarted by a small motorbike engine on it I have looked into alternatives. And lego can fuck off - somewhere in out family is an old style box of lego you can make anything (non-thermal) with but now a kit makes one thing and one thing only. Largely because you cant afford anything else!
