ROALD DAHL DAY SCIENCE – ROCKET BALLOONS
We worked in teams.
We observed what made our balloons move – the power of air pushing the balloon as the air rushed out.
We learnt how hairy string slowed down the balloon. “This is friction,” explained Jayden.
Alexi even tried to cut away the hairs to make the balloon go faster.
Lilly-Mae suggested to wrap the string in sellotape because it is smooth which will make the balloon move quicker.
