Unless you have a mountain of black balloons that you need to pop, this DIY project serves no practical purpose – I am not sure whether that makes it more, or less, awesome. There are instructions if you want to make your own. Note that in the video the maker recommended the use of protective eye-wear, that’s because the laser would probably do to your retinas what it does to the balloons. Getting a nasty bit of laser reflected laser probably wouldn’t be too nice either. Seriously, play safe. [DVICE]
