Last week the ovals made a balloon powered rocket. The force of the blown up balloon made strong air that launched the rocket balloon to the end of the string.
One of our challenges was to see if the balloon is better going up but it only went half way.We learnt that the balloon goes down better than up (eg it's like going up hill it's harder than going down) .
