Needs must and my eldest sons science project calls for my 40K (and some) "Space Wars" planets to be scrutinized for stand in Solar System duty. I had to knock up Mercury from a small polystyrene ball destined to become an asteroid or minor moon [first rock from the sun], repaint a green planet with some earth-like oceans for you guessed it Earth [third rock from the son] and then repaint another green planet to blue for Neptune [last rock/gas planet]. Work in progress, the planets get an identity parade line-up (see below):
The backdrop was the reverse side of a game board I luckily (or was that great 'male' foresight at work?) had painted black, The family, three children armed with defunct tooth brushes dipped in white paint "splattered" stars and the like onto the backdrop. Great fun until we looked at our shoes the next day and saw lots of "white spots" of them. Pity the kids wore their best shoes (ahem), I was not popular!
Another view of Sol's planetary system without the dangling strings on Sol ;)
