Introduction: Mousetrap Car
Mousetrap motored "cars" are not always easy to make. These instructions will contradict the previous statement.
Step 1: What You Will Need
You will need: for our body we used K'nex These materials can easily be substituted.
-1 long, grey rod for the back axel
-a shorter, red rod for the front axel
-4 rubber tires
-4 orange, rectangular pieces,
-and 6 small, grey pieces, all from the K'nex set
Attach the 4 rectangular, orange pieces to the 2 widths of the mousetrap with force. They do not need to be fastened with anything further.
Slide the 2 rods in the front and back pieces
Attach 2 grey, smaller prices to either side of mousetrap on axels to prevent movement. Slide on and hot glue back tires to axel. Repeat for front axel.
Tie one end of string to the mousetrap trigger. Next, wrap the remaining amount of string around the back axel, making sure it's secure.
After you have set trap and wound string around the back axel, let go and let fly!
