SOOOOOOOOOO WE FINALLY BUILT A DECENT CAR ! YAY ! :)
We put parts of our cars together to make a ballon car that works very well !
BUT the only problem is making it travel in a constant direction ; to make it travel in a straight line.
materials we used :
knex wheels with some other knex material like the sticks, BBQ sticks, straw, string, and cant forget the balloon !
P.S. this is the 4th car we SHOULD have raced with for race day.
