We created a hoverbord that could survive in a Sci-Fi world where 80% of the world is lava.
We made our first prototype out of cardboard and tape. It had cardboard fans and also used a fan for steering.
Then we added a fan that was pretty weak and didn't budge. Then we made it out of thin wood and added even better fans that would go berzerk if you didn't hold it.
Our final model was mad of foamcoare and had domes to protect the fans from little fingers.it was RC and had a steering fan and rudders for steering.
