The black box required to be light whereby it can carry up to middle air by 6 helium gas balloon, thus i decide to redo my black box, hope it is really light enough to fly up.
Well, i used bamboo stick to make a hexagon shape whereby only one balloon can pass through it one time, then i used plastic bag to carry 6 balloon and the paper on top is used to cover the balloon from fly out the bag.
