About

ZEN BUBBLE

Read full description

Work is over, but your mind is still at your desk. Thoughts pile up and you can’t quite put them down. ZEN BUBBLE is a small lakeside world you can step into whenever that happens. Exhale slowly toward the microphone, and bubbles rise and drift out over the water. There is nothing to sort out, nothing to fix, and no mind to empty. Just breathe out and watch. WHEN TO OPEN ZEN BUBBLE - You’ve been overthinking and your head feels worn out - Work is over, but your mind is still at your desk - The same worry keeps coming back - Your head is still loud after being around people - Anxiety has made your breathing feel shallow - You’re tired, but your thoughts are keeping you awake A LAKE THAT CHANGES WITH YOU The lake follows your local time, season, and weather. If it’s raining where you are, it rains there too. Snow, full moons, and cherry blossoms arrive here in sync with the real world. A cherry tree grows on the days you take time to breathe. Songbirds, fireflies, foxes, and other seasonal visitors appear throughout the year. You can keep track of all 30 creatures and 6 plants in your field guide. LET IT OUT If something is stuck in your head, tap the ring and say it out loud. Your words float away inside bubbles and disappear when they pop. A copy stays in your private journal. A RECORD See the minutes you’ve breathed, the bubbles you’ve made, and the thoughts you’ve released.
