If you have ever attempted to swallow a mattress or have forgotten to remove clothes before ironing them then this book will become a vital survival tool. For the rest of us it is a collection of the oddest, funniest and frankly most worrying instructions taken from genuine products around the world. Manufacturers from Turin to Tokyo seem truly concerned that we know their products may be hot after heating, that we should not place fireworks in our mouths or that we should really not use a hairdryer whilst showering. And please remember, your new toaster should not be used underwater.
