Simon was bored, it had been a boring start to the term and now he wanted to have just a little bit of fun. He remember about a prank that his friend had told him about in the summer and now was the perfect time to pull it.

Taking out his wand he decided to spray water all over the floor. "Aguamenti!" Simon did the wand movement and then he sprayed it good and proper, he hoped that no one would come whilst he was doing it. He thought he might get into trouble if someone got water on them because of him.

He thought about what else he would need. "um, so I'm doing the water now, but what can I use to make the floor slippery." He totally wanted to make a water slide because how epic would that be.
