If you have stuff dry cleaned, you know those bags I'm talking about.
thin, filmy, almost insubstantial, but still potentially lethal to babies, small children, and pets.
I don't have any babies in the house at the moment, but I do have a dog, so I try to dispose of those bags safely.
Here's how I do it:
First, smooth the bag into a long strip, by running my hand down the length of it and twisting.
Then tie knots in the bag every few inches.
Tie the knotty strip into a couple more knots, just for good measure.
Then throw it away.
This way, if the bag does manage to sneak out of the trash can, it is too compressed by the knots to be a safety hazard.
Of course, if your dog (or your child) manages to swallow it, you have another problem.
But that is another post.
