Trixie raised her hand high, as a sixth year student she was more then willing to show the spell for the newer and younger students. "I'll volunteer professor" she grinned looking around at the other students that had offereed their services. Weren't some of them first years though? Had they even seen the spell be used before? Still it was great to see the amount of people that were volunteering anyway. This was what their classes were about wasn't it?
