The Raven balloon

theravenballoon.jpg

Here Andre is bringing the balloon outside, ready to launch. The box he is carrying contains much more plastic: what you can see is a small amount of hydrogen inside the top of the big plastic 'Raven' balloon (it feels like its made of plastic food wrap). As the balloon goes up in the atmosphere, the gas expands until all that extra balloon is filled. The balloon will be about the size of a football stadium when it bursts, somewhere near 30 km.
