On Thursday 4 August we made a balloon car for a science project  and I had to get a lot of bits  for my balloon car and then I got a  long 1.5 liter bottle for the bass of my car then I some sissors and cut some hole’s for the toothpicks for the bottle gaps of the milk bottles then I got for straws so then I can blow the balloons up.for the milk caps you poke a hole in with a nail and I got two balloons the balloon colours  were yellow and  blue.my first try with my balloon car it went 88 cm my second try went to 77cm my lucky last was 400 m and  380 cm  and it was flying a little bit .thats how I made my balloon car . by Caitlin
