Ok, so I bribed Alan.
He was being lazy all day, and his sisters wanted to go in the pool and he didn't, so, I told him I would make him a little wooden battleship if he would go swimming with them.
It worked.
He went right into my workshop and grabbed some sandpaper,
"I'll help you sand it!" he said.
So I put together a quick battleship made out of pine. It took about 45 minutes. I had read somewhere that pine holds up really well in water and that it's good for making wooden bath toys out of. We'll see.
