The air skimmer was pretty easy once I really took a look at the directions and broke it down (and maybe received a little bit of help). I thought my air skimmer looked cool when I was done because of the sharpness of the folds, but I had some difficulties figuring out how to make it go. The rubber band wouldn't stay attached to the bottom long enough to let it glide across the floor, but I eventually got it to go. The first couple of times I shot it, it did a couple of flips in the air, so I had to put a paper clip on the front so it would stay down. I ended up getting it to go a total of 49 feet.
