The $2 Altimeter Test Chamber

How to test your barometric altimeter with easily available items from your kitchen.

I will not explain how this is made or why you would use it. If you can't figure that out you have no business flying rockets with electronic deployment.

Special thanks to Burl Finkelstein. And to his wife Joanna, because if she didn't do home canning (or if she'd hidden her Mason jars away from Burl) this contraption would not have been possible.
