We have one of those big things on our lawn that you see nearly everywhere, the big, inflated snowman (or Santa, Christmas tree, Grinch, etc.).
They are actually kind of cool. You have to leave them plugged in for them to stay filled because a fan is at the bottom constantly blowing air up inside of them. The shrink down flat as soon as you unplug them.
I enjoyed watching it fill back up the first couple of times. The big base would fill first and then the upper part would slowly work its way upward like a snowman that's had one too many frozen mudslides.
He is outside laying flat after we lost the battle with the ice and sleet. It collected on the brim of his hat and slowly bent him over backward. I hope he'll thaw enough to inflate tomorrow when this is done.
