i can use:
1 piece computer paper;1 piece construction paper; 10 popsicle sticks, 4 drink container lids; 1 coat hanger; 6 toothpicks; scissors and plies, and wood glue. the car has to travel 3 meters and must stay within a 1 meter wide lane. it will be blown by a box fan 9 times: 3 times on high, 3 times on medium, and 3 times on low. the fan can be placed anywhere behind the car before the trial begins. the faster it goes, the better. any ideas? would be appreciated. thanks.
