Martian Matter

Thanks to Aunt Denise, Finn is having a blast with his MARTIAN MATTER that he purchased with his Target giftcard. He felt like such a big boy paying for his own toy!
Now, Finn tells me we need to make the solar system and some space ships for his Martians.

I'm going to have to get a little creative with that since we've pretty much depleted our craft supplies over the past few weeks of cold gray days. We've got an abundance of paper towel and toilet paper tubes though...hmmm, how can I make THAT work?!?
