Both teams miss their target and the last remaining grey gobstone in the circle still sits on the edge.

OOC: Ravenclaw posted 2 answers, four minutes apart, which would normally be a penalty, but I always give a warning first. None of the given answers were correct, though krazypenguin's was closest. I was looking for specific people who helped Harry directly before or during the tasks (i.e. Barty Crouch Jr, Hagrid, Dobby, Hermione, Ron, etc.)

Toast and marmalade.

Ravenclaw slides their stone gently into the circle, while Hufflepuff simultaneously does the same. Which gobstone will make it to the grey stone first? RAVENCLAW! They bump out the stone, which spews gob all over the Badgers, and they win the round and match! Eagles will go on to the Championship! Excellent efforts made by Hufflepuff!
