Did you know that you can make a case for your phone using a balloon? This is interesting and tricky to make. Using aballoonis a fun and easy idea, though I don’t think the balloon outside your mobile phone, especially those smart phones of high prices, will look good, but it is really a nice temporary water-proof solution when you need a phone case badly such as when you are camping. And what’s more, it will be a bizarre to show off this trick in the party ;). Having fun there.
