Getting different value in array what I push

I am working on angular project. I am facing error that last value of object shown in all array.

$scope.products = [{"product_id":"1", "price:80"},{"product_id":"2", "price:90"}]

Now i am using angular forEach method. actually I have much thing I product array so i use a order array where I I provide just id and value

angular.forEach($scope.products, function(value, key){
   $scope.order.product_id = value.product_id;
   $scope.order.price = value.price;
   $scope.orderProducts.push($scope.order);

})

but I get

$scope.orders = [{"product_id":"2", "price:90"},{"product_id":"2", "price:90"}]

on my console I saw

objet{{"product_id":"1", "price:80"}

but when I open then I get

 product_id:"2",
 price: "90"
