Five-year-old Charlie had been following the 50th anniversary of the moon landing. For Halloween, her parents build her a Lunar Lander costume! Charlie's little sister, two-year-old Ellie, is an astronaut.
Charlie enters the costume by crawling underneath and there is a pair of shoulder straps that she uses to lift the entire costume. The costume looks heavier than it is -- it's almost entirely made of foam and foamboard. The front hatch magnetically closes and magnetically stays open, and doubles as a candy sample input port. The ascent stage (top part) separates from the descent stage (bottom part with landing pads) as you'll see below.
