Rule no 1 in scratchbuilding : no need to spend energy if someone else built it for you already. If those toy chutes can do the trick... don't hesitate.
I just remember when I was a kid, (in the sixties or early seventies) we used to have these small plastic alien looking figures (quite cute actually, about an inch tall) with a small parachute. you could throw them up in the air, and they came drifting down on the chute. You know what ? I'll try to make one of those for junior tomorrow !
