What is the operation of inflatable Christmas decorations?

When it comes to giant christmas inflatables, the most pressing question on people's minds is, "How do these things even work?" How do they manage to stay inflated and upright all the time? While it is not Christmas magic that keeps them standing, it is still quite impressive how they function. The inflatable Christmas decorations include a fan that draws fresh air into the inflatable. The air circulates inside the decoration, keeping it expanded and shaped. The Christmas outdoor inflatables are made of nylon, which allows air to slowly escape and prevents over-inflation. The inflatable will remain inflated as long as the fan is not covered or blocked. We've included a handy diagram to demonstrate how the inflatable pulls in.
