not so much a recommendation for the enjoyable/realism factor but as for a tip...
If you aren't already doing this, I find to secure the trash bag for inflation, cut a somewhat durable rubber band and use that as a string (pulled taut) around the trash bag over the air hose. Keeps it firmly in place and doesn't let air escape while you're inflating. Like I said, an easy one that probably everyone does, but it took me a couple of experiments early on to more effectively figure out how to tie off a trash bag to inflate.
