The Swing Toothpaste uses inertia to make sure you get every last bit of paste onto your brush.
Your finger goes through the hole in the end, where you to twirl the tube, allowing centrifugal force to push the toothpaste toward the cap. I think it’s a very doable design and adds a dash of fun to the brushing routine. Maybe even motivate children to keep up with the dental hygiene!
