Enough to blind you if you're looking up. That's why it's dumb.
As kids, we used to fire vertically upwards regularly with the specific aim of having the pellet land somewhere near. That very rarely happened - and when it did, the best we could achieve usually involved us hearing the pellet land yards away. Dumb it may be - but not dumber than all the other dangerous things we used to do.
