Ok, this isn't that hard. She glanced around to her colleagues and could spot a few familiar faces nearby as she kept walking to an empty portion of the lake's shore. She set her jar in the ground, stretched her arms above her head and gave her limbs a good shake.

Let's do this! She tested the whip-like movement with her wand a few more times before adding the incantation words. Carpe Retractum, Carpe Retractum, Carpe Retractum, Carpe Retractum, Carpe Retractum...

"KAHR-pay ruh-TRACK-tum" she tried out loud a few more times, working her pronunciation. This wasn't that hard.

She took a deep breath, focused her gaze on the lake and combined with the whip-like movement she cast the spell "KAHR-paaay ruh-TRACK-tum". But nothing happened, no Golden/Orange Light, no nothing. Buggers.

She scratched her head and looked around to see if someone had managed it to work yet.
