That's what you'll get for $107*. You pay the premium to have it all packaged together (and presumably get some sort of instruction sheet) but there's a good chance that between school and home, you have a lot of these items anyway, and a trip to a dollar store or hardware store can fill in the rest. As previously stated, this is a great starting point, and students will be able to build a functional, competition-ready hovercraft. Hopefully they'll find ways to improve on it the more they test it.
*Chalker, can you explain how this price point is set? I assume there's some partnership between Ward's and SO Inc., and this is good business for all parties, but, $107?! Frankly it seems like it's $7 worth of stuff and a $100 packaging fee. If you're contractually obligated not to discuss this, I get it, but all of the online kits seem dramatically overpriced.
I'm not involved in the pricing in any way, but I can share some thoughts on this:
1. Nobody should ever pay the list price for a Ward's Sci kit (or really any science / educational material). All the big companies that do things like this set high list prices then provide lots of various discount codes. There's a code printed in the front of the Rules Manual for 12% off. I know there are other codes floating around for larger discounts as well.
2. Wards does have to recoup labor costs and there is also a certain amount of funding returned for Science Olympiad as well.
3. You're significantly underestimating the cost of the materials. The axial fan, which I've given details on before, costs ~$10 alone. The 9V batteries cost ~$2. Altogether there are something like ~60 different pieces that are included in this kit, which includes extras of things like the foam plate and zip ties so you can build different versions of the hovercraft.
