Lily @ Potions contest
Heck yes Lily went in for the Potions contest. It's right up her alley AND she'd love a chance to ask Belby some questions about what he's working on.
Lily brewed up fingerpaint for little ones that changes colour, is safe to eat, AND quick and easy to clean up (even off clothes or walls). For bonus cute points, she enlisted Harry to help demonstrate and he left colourful tiny handprints on her face and on Belby's robes.
