We were learning about what is action and reaction is and then we did balloon madness that links to action and reaction and for the balloon we had some string a bit of straw and a balloon. Then we got the piece of thee straw and thread throw the line and then got the balloon and taped it on to the straw. Ttheen we blowed up the balloon and let the balloon go and boosted up the line and then came down the line like a zip line.
I found it hard to make the balloon go up the string because we did't know how much air is in the balloon because we thought the a lot of air in the balloon would make it go high and a small amount of air would make it go slow and not long but the small amount of air go's longer.
I observed that so people had two balloon on the rocket and it made it worst because the balloon just spun around in a circle did nothing cool.
Next time I will try to balloon going up high and putting them in the right angle so they don't go bad and spun around.
