Weather Balloon

During the building of our weather balloon, we got a helium balloon and began to build a payload. We attached some string, cut out a small sized zip lock bag into a circle and made it into a parachute. Then we attached it on the string. Next, we made a small paper camera and put it a little bit under the parachute. After that we made a little payload box and attached it to the string under the carmera. We put a tracker on the payload, and paper clips in the payload. After that we attached string to the bottom of the payload to then to see how high it can go with out it flying away. Lastly we weighed it and it weighed two pounds.
