How can you not like bubbles? They're cheap, pretty and a lot of fun. Izzy's really into them. She'd really love to have one of those human-sized bubble hoops that can make bubbles big enough to get inside of. Though she's also slightly afraid she'd get trapped inside of a bubble and it'll float away with her in it.
That's nothing to worry about now. Normal sized wand. Normal sized bubbles. Nothing's carrying off any children today.
