IF she wanted to experiment on them? He clearly did not know her, Isidora always ALWAYS wanted to experiment with any and everything. Especially when they were muggle things. "I really do, professor." She nodded eagerly and opened up the little door to spot the bag that West was talking about.

"That's unfortunate. Having to buy a new bag every time," It really was a shame they didn't have magic, else they could just conjure up more bag. Oh, and Sarah was talking now too. Dora drew her wand while looking over at the girl and listening intently. "A container? What's it made of? How much can it hold?" These were things she needed to know. Also, how cool was it that she had a muggle grandmother? "I don't have any muggle relatives. That I know of at least." She didn't even know all of her family, so who was to say she did or didn't have them.

If she did though, that'd be awesome.

West did, she made note of it for later times.

She wasn't worried about opening it since she first wanted to test out the capacity of the bags. Aiming her wand at the bag she focused all her intent on the one spell. "Finite Incantatem" Almost instantly she could see the planets bouncing around in the bag, more limited on the space now that she removed the extension charm. Whoever had this bag didn't catch all that many though.

Poking the bag lightly, she suddenly noticed that planets were flying around. When did that happen? She looked around and.... oh, sure. West. She grinned and closed her little door, tugging the vacuum off the floor.

"I'll get them all, professor!" And test out her bag at the same time. Win!

Dora went after the planets eagerly.
