“It was very dirty and had all kinds of cobwebs inside. I cleaned it out and even found a bunch of black widow spider eggs inside the tube.”
I bet if you took it out in the middle of the street and pointed it at a police car you’d get a reaction. :)
But, no, empty LAWS tubes are not illegal or dangerous.
I bet you could turn it into an excellent spud launcher. That would clean out the spider eggs, too.
FOOP! There's nothing so satisfying as watching a potato fly across the field and into the pond.
I feel sorry for kids now. They aren't allowed to have any fun.
