Squeeze the bubble out over and over again when you get stressed or bored and kill time.
Just press the mouse bubbles and they will make a slight popping sound; then flip them to start again.
When you are too tired in daily life or work, pushing and pressing bubbles can relieve stress, worries and anxiety.
Small enough to carry with you everywhere and everyday, also you can be attached to your keys, backpack, cellphones or other electronic devices.
Great gift for everybody.
