A global movement spreading Jewish joy, unity, and kindness, one duck at a time. Hide a duck, find a duck, share the smile.
If hate can go viral, why can't love?
Ducks have turned up in 18 countries, carried by the people who found them.
Every photo here was sent in by a Quacker who found a duck out in the world: a car wash in Carolina, a cruise buffet in the Bahamas, the Chagall windows in Jerusalem.
Every duck lands in a real moment. Here's what a few finders wrote back when a small blue duck turned up saying שלום.
My mother just passed, and I was asking for a sign… the first thing I saw was the Star of David on its head, then the Hebrew on its chest. I believe it was my mother telling me hello, and that she’s now at peace.Anderson, South Carolinaa finder at a car wash
It felt like a gift. A pause. A reminder of peace that landed exactly when we needed it… You created a ripple of joy for my family that we won’t forget.Union County, Georgiaa hiker by the falls
I went with friends to buy a bottle of whiskey for Shabbat. What a surprise to find this adorable duck… I keep it in my car, looking out over my travels.Katzrin, Israela Shabbat shopper

the sightings map
A duck at the Chagall windows in Jerusalem. One at Times Square. One riding a cruise at sea. Every pin is a Quacker's photo, and every photo is a little Jewish joy passed along.
spotted in the wild
New sightings, new ducks, and the latest drops, on Instagram and Facebook. Found one? Tag @kosherduckrevolution so we see it.
how a drop works
Tuck a duck somewhere a stranger will grin to find it: a park bench, an airplane tray table, the rail of a cruise ship.
Every duck comes with a tag, and the tag carries a QR code. Scan it and you land on the page where you put your duck on the map.
Snap a photo, add it to the map, and hide the duck again for the next person.
One duck, many hands. That's how a rubber duck turns up at Times Square, the Chagall windows in Jerusalem, and on a flight over the Atlantic.

Jewish pride, out in public, one smile at a time. A duck under the Chagall windows in Jerusalem. A duck on a cruise buffet in the Bahamas. A stranger who scans the tag and writes back. If hate can go viral, so can this. The doors are wide, and the Jewish core doesn't move.
