Launching from the Moon

My group Clara, Emma S. and I did the lab "Launching from the moon." Our goal was to get a balloon to go up a piece of string and to hit the wall. Our first attempt was to tape the end of a balloon to a straw. Our first attempt was a failure because the balloon didn't go anywhere. As the balloon deflated it stayed where it was at the entire time. Our second attempt was a success. Instead on taping the end of the balloon to a straw, we taped the middle of the balloon to a straw. As the balloon deflated it went up the piece of string and hit the wall.

My group and I learned that this lab was an example of Newton's 3rd Law. Newton's 3rd Law states that "For every action, there is an equal and opposite reaction." As the air from the balloon escaped, the escaping air pushed the balloon up the string.

Our last attempts did not work successfully. Our goal was to lift objects (ping-pong balls, bateries etc.) up the string. We tried atatching multiple balloons to a straw and taping the object to the balloons. Those attempts were failures because the objects would fall off the balloons or the balloons would not go anywhere. I think that this was a fun lab. If i did it again I would like to see what my group and I could have done differently to lift the objects up the string.
