Lightbulb Waterproofing Electronics Discussion

In thinking about Reed Timmer's recent success for getting an electronics sensor package into a tornado using a Quest Magnum Sport Loader (3012), I've been thinking about how I'd do it.... Tornadoes frequently are rain wrapped, and I'm thinking that to protect the sensor it could be inserted inside a large uninflated balloon (clear being the best color option). I feel that it shouldn't affect the electronics ability to do pressure sampling, but would greatly reduce the chance of water infiltration of the unit greatly increasing it's lifespan and preventing data loss.

Another option could be to use a condom, but that's a lot thinner, and I'm thinking that it could be more easily damaged. Balloons can be bought in packages of 100 (or more), and a single color (and likely for far less than a supply of unlubricated condoms) . I know, I've bought several thousand balloons over the years in my street preforming days and a bag of 100 is typically less than $10 USD from a wholesaler.

The only concern I can think of is the powder used to keep balloons from sticking to each other (and the insides to themselves).

I also think that (at least in his case) a piece of foam could be glued inside the nosecone (for buoyancy), and a couple pieces could be wrapped around the electronics to prevent it from being damaged from being bashed about should the unit come down and snag on something while the wind is still strong.

So, am I onto something? Would this work for us with our applications (say launching at BONG)? Or am I way off base here? I don't remember seeing any discussion on this topic directly.

Dreaming of making the rockets I dreamed of as a kid (and then some).

"The Guide says there is an art to flying", said Ford, "or rather a knack."
"The knack lies in learning how to throw yourself at the ground and miss."

Launching is Optional... Landing? That Depends on Trees.
