At the windtunnel we tried to use the watering can as a smoke nozzle/ machine. The can is filled with a smoke-cartridge and airflow should go in by the same hole. The smaller exitpipe where normally water comes out, should draw the smoke (or parts of it) out. We made 3 tests to make it happen. (see the other videos)
This video has the parts of the actual soundtrack. Since I have done experiments with the filmspeed and the windspeed, neither sound nor image are in sync.
