This was a hit at a 4yr old birthday party.  The perfect size for a few kids and adults and super sturdy; we had some future s/he-mans yanking on the handles with all their might.  Play some music and do freeze dance, have the kids try to all run under before it goes down, are they fast enough?  Other fun games - through some ball on top and don't let them bounce off.  There are probably many more ideas out there if you search the world wide web of fun.  Now I am waiting for another turn where we have enough people over to use it.
