Small satellite to be launched by high schoolers

Hi,
My team and I participate in the CanSat in Greece 2018 competition. We have to construct a can-sized satellite (actually it is not a real one as it will not get into orbit) and launch it at a height of 1000 meters! We are currently in the 10 best teams of Greece. Part of our mission for the competition is promotion. If you want to help us gain points and would like to learn more about the competition (which is not unique to our country and not necessarily for high school students btw) you should:
