If you've ever fancied a cheap phone case for the new smartphone that could be just what you're looking for.
1 - pop the balloon and attach the phone about it.
2 - Then, a person must freely hold the opening shot, while the other holds the phone.
3 - Soon, the balloon begins to mold in the shape of the phone.
And that's it. Your new phone case is on.
The only drawback is that unlike most cases you will not have access to various ports on your phone and headphone jack.
And while you may not want to keep this case on your phone for a long time, will at least make a good party trick.
