Scientific summer

Well this summer i did not do a lot of scientific stuff i did two scientific things first i went in this huge ball whit air in it and i was on water.It was hard to walk in it if it wold be in the ground it would be easier the second thing i did was it is this thing that goes up and down it was vary scary but cool at the same time this thing had kinetic  energy it was really fast so every night of my summer i would go to the Luna park and it was fun of course. the thing that was scary the thing that would throw up in the air was called matrix the first time i did it it was freaky but it makes you throw fortunately no one throw up it was just strange being up their but the gigantic ball was taring you could pay and do 3 min if u paid twice 6 min you always fell when you tried walking i tried but for a seconds you could do a summer roll that was fun doing it.

in this the science was in it their was kinetic energy and friction it was hared becuse the ball was on the water and not on the floor i think 3 min was enough becuse once we did six and we were sweating ther was air but it was hard to breath and when you breathed the air seemed.
