Harry followed the length of the semi-tublar slide with his eyes. He caught an occassional glimpse of a hand, fingers splayed wide, or a foot, kicked up in surprise. He was torn between apprehensive wincing and amused chuckling.
Then came Severus slipping of the end of the slide into the pool, with all the grace of someone having been pushed off a cliff. Harry held his breath as Severus resurfaced and turned to give a critical eye to the waterslide.
Tentatively, Harry asked, "Wanna go again?"
Snape, still eyeing the slide with a challenging gaze, responded, "Try and stop me."
