bopping a balloon is really funny

Sylvia's started laughing more and more, and it's unreasonably cute :3

It's not obvious ahead of time what she's going to find funny, and sometimes she just laughs when other people smile or laugh around her.

But: while we were on our trip, she found it *hilarious* when her little cousin Penelope was bopping this big mylar balloon.
