The difference between the squeeze rubber duck and the floating weighted upright rubber duck

Ordinary Squeeze

Without the weighted, the duck will be dumping in the water.

What is more the water will flow into the body from the hole so that the duck will drown in the water

Weighted Floating Upright

Increase the weight of the duck bottom to ensure the duck floating upright in the water.

Floating upright means keep the head upright. So that the duck will be advanced in the racing.
