Its a con Crispin!  Those rocks look inflatable to me, at least you can 
see a seam!   And I strongly suspect that the coffee table would show 
scorch marks, as well as adding considerably to the cost!

How many millenia have the women been waiting for the men to get round to 
improving their cooking fires?

Is THIS a better reason for disbelief we ever landed men on the moon?

Best wishes,  Neil Taylor (who still has trouble that the primus stove 
was invented at the end of the 19th century, the TLUD about 100 years 
later, (maybe?) - and now this - the new stone age!  ;-)
