My son likes music too, and art, but he gets interested in science now & then too.
He's recently been talking about it enough that I think I'm going to get him a nice telescope for his birthday - as soon as I learn enough about the products to feel like I can pick one & the right accessories.
And, we have a science museum close enough by that we could visit anytime - they have a big dome theater that shows IMAX movies, so he said he wants to go to that too. He's told me no a million times over the years, to the point I'd stopped asking. But, just the other day he said he'd love to go. Of course, he could back out of it as soon as we hit the parking lot, but I'm going to try it sometime soon.
