Bubble Wrap

Many people (including myself) simply can't resist popping the bubbles from bubble wrap. The problem is that if you do that, it becomes useless and it will no longer protect its contents.

Bubble Wrap is a tiny Java application where you can pop as many bubbles as you wish without any other consequences than possibly ruining your mouse button.
There's not too much that can be said about Bubble Wrap. It's a Java game so you will of course need to have Java installed on your PC in order to play it. The application is very small and requires very few resources, so you will be able to run it on any type of computer.
A thing that flustered me when I first launched Bubble Wrap was the fact that it starts up minimized. The only visible thing was the menu bar and it took me several seconds to figure out that you need to resize the window to make the bubbles show up.
At the end of the day, Bubble Wrap is a great way to kill some free time and even let off some steam. It can be a bit addictive, but you can pop a few bubbles even while working, so I'm sure you'll be fine.
