Hey there !
we have a question with our experiment.
well, we are from germany and had chosen different kinds of chemicals. we want to see the changes and reactions in the ozone layer. But the big question is which chemicals we can choose?
Also we want to start our balloon at the 13th april this year and we have not much time.
If you can give us tips or ideas, we will be very greatful.
similarly, it will be very nice if you can tell us a short summary of your experiments.
Greetings from
The Mission->Atmosphere
