Sunny watches as Magnu's balloon explodes. "Wow." He's big strong. Sunny wants to try, so she takes another balloon and thinks of something really awful to blow up. "Fires," she settles on and tries her hardest to throw the balloon as hard as Magnu did. It doesn't have quite as intense of a reaction (a phrase which here means, 'it sort of just does exactly what her other one did') but she's pleased with the outcome anyway.
