A/N: Set during OotP (pre-twins' leaving) just a little idea that randomly sprung to mind. Short little one-shot to celebrate my finally posting a fic.

It was a late Saturday night when Professor McGonagall walked down a long stone corridor on her nightly round and noticed that there weretiny explosions coming from behind a tapestry on her right. Curious to find the source of the noise and what someone could possible be doing this late behind a tapestry, she drew her wand and pulled the tapestry aside. It revealed a rather small room, full of smoke and multicoloured sparks. There were in the middle of the smoke weretwo red heads of hair, which doubtlessly belonged to the Weasley twins. Dodging a flying spark McGonagall lowered her wand.
"Weasley and Weasley, what in the name of Merlin are you two doing?"
They turned at once trying to hide their guilty faces and conceal their newest product: Weasleys' Wildfire Whiz-Bangs.
"Well you know Professor" the twins replied, "curiosity killed the cat."
