Oh yeah! Much better idea, thanks. Probably easier than hunting for muggle fireworks when it isn't July yet. And of course I'd be happy to help teach them how to cast it, it's sorta one of my favorite spellworks to do here.
I think I saw a couple posts of people who can suddenly do magic, so we could probably find them. I'd bet they'd jump at the chance to use magic for a birthday if given a chance.
