Two known facts: 1. I like weaponizing houesehold items 2. I do not like witches So I though I can make a slingshot crossbow that fires straw brooms. So you can give the witches a taste of their own medicine and fire brooms at them while they play their sick Quidditch game!

I will need a looong, heavy launcher for the 1 kg heavy brooms. I am thinking 3 meters, maybe 100 kg (220 lb) draw weight. That should launch a broom about 60 meters up into the air.
