I took the cubs to a science/ discovery museum in Charlotte when they were about 6 and 8. Boy cub, the 6 yo, was missing for a minute. I noticed that the same recorded voice kept coming from one of the displays. Sure enough, cub was repeatedly pushing the button to hear the recorded guy talk about Uranus.
"Uranus is XXXXX miles wide." followed by the cutest hearty little boy laugh.
Of course, sister rolled her eyes and told him to grow up.
I love Uranus.
