K'nex simple machines kit

I would like to raise $375 to be able to purchase the K'nex simple machines deluxe kit for my students. My school does not have the funds to purchase this kit and I would like my students to have the opportunity to have fun while building machines and seeing how they function.
My students are very creative and have been asking to do a project on machines and building them since September.  I don't want to disappoint them.
The kit includes instructions to build 60 different machines and information about them and how they work.
