|My First Mousetrap Car Design|
|Current Design I Use for Classes|
My next series of mousetrap cars were constructed in a more conventional way from balsa wood and using four CD wheels with faucet washer hubs. This car was used for a College for Kids class and worked pretty well except the lever arm constructed from balsa glued to form a T-structure was not strong enough for kids to handle. Also the faucet washers I had bought in a hardware store did not fit the hole in the CD tight enough.

|Balsa Lever Arm Broke for Students|
For the next year I used a heavy dowel for the lever arm and I came up with the idea of cutting chunks from tarp straps for the wheel hub. The dowel lever arms did not break but the students had trouble attaching the lever arm to the wire on the mousetrap with hot glue and string. For this summer's class I have the lever arm already attached. Hot glue takes sometime to setup solid, for impatient kids this is a problem. Since last year's class I have also created the chassis for the car from foam cut with a hotwire.

Much can be learned from struggling with a design but for a class where there is limited time and no one to help assist the students I find it better to refine the project. It is my hope that the students will be inspired to create their own mousetrap cars if the first one was a good experience.
