I am involved in the Vacation Bible School at my church this year. This year's theme is Star Wars. The church is making many props and objects for the VBS that have the Star Wars theme. I am actually helping constuct two hovercrafts for this VBS. One will hold two people and be for show and the other with hold about 10 children so we can cart them around the camp. We will make them to look like Star Wars pod racers.
A good website that we use is
Universal Hovercraft. This comapny makes and sells many different sizes and shapes of hovercrafts. You can buy plans for hovercrafts, or buy ones that are already made. It is a very useful website.
I hope this helps. If you have more questions, let me know.
