"Race Across the Hallway" Hovercraft U-Designå¨ Challenge
KELVINå¨'s updated model of the Hovercraft has the ability of hovering over land and water. This innovative hovercraft is designed with an external power source that allows the hovercraft to run 50% faster for a longer time. Now you can design a hovercraft that not only lifts and travels from one point of the room to another but can also float in a pool and glide across tile. Both the Basic and Competition 2009 Hovercraft Design Challenges™ are great construction projects that demonstrate lift.
This kit includes: two types of motors, foam trays, two propellers (one for lift and one for propulsion forward), 9V battery snap, slide switch, wire, dowel rods, craft sticks and clips. Also optional, not included, wired remote control battery pack with On/Off switch and 10ft wire.
Kits require designing, soldering, assembly and evaluation skills. Also requires 9 V battery or remote battery pack (#851510). Grades 6 and up.
