My weather balloon payload is 9 1/4 inch x 9 1/4 inch x 2 ½ inch and is capable of surviving an eight feet drop test with no damage. The camera is located on the bottom so when the balloon payload is floating up, it will capture the earth going up. The other equipment and devices are located inside the payload and is surrounded by thermocol, (100% recyclable) so the pennies in the mockup won't burst out. I have tested this multiple times and it has always been successful.
