This sunday, on Port Meadow, timscience and myself will be finally carrying through on our long-term threat of introducing a solar airship to a baking powder rocket. As you can see from the diagram above, I have done a full risk assessment and decided inviting onlookers would be desirable and fun! You may wish to bring sturdy shoes and recording devices. And if it's not Youtubed by the end of the day, I will be very disappointed.
In the event of technical failure of either or both elements of the experiment -- what are the chances, eh? -- or rain, hail, sleet, snow, etc. we will retire to the Perch and complain about the weather.
Projected launch window is 2.30-3.30pm.
EDIT: More details and a poll on the possible results of the experiment are over at timscience's.
