So there was probably a list of Top 10 things you weren't supposed to do at Hogwarts posted somewhere, and what she'd come up to the Astronomy tower to do probably would have been somewhere on it. Maybe high on it too, unless the Tower had the same enchantments on it as the Climbing Tree, considering dropping objects of the side would probably gain some speed to hurt anyone below.

Which was not the goal. The goal was a muggle physics experiment of sorts. She wanted to know what fell faster and if the differences in falling was big or like... Minor. But the other goal was also to see if there was something that would slow things before they hit the ground from this high.

Pulling her bag of items closer on her shoulder, Ve glanced out one of the windows towards the ground below - before rummaging around in her bag and pulling out something small. An eraser first seemed safe. She put it over the edge and released, calling out as she did so, "Watch oooooout!"

See! She was being safe!
