Does your marble need some speed? If so, the Hubelino Gravity Hammer is here to get the momentum flowing again. This hammer has enough force to move your marbles up several levels! Once the gravity hammer is installed, rotate the part with the metal ball upward so that when any approaching marble subsequently bumps against the gravity hammer, the metal ball will swoosh down and knock the marble forward. This cool Hubelino extension offers a great lesson in momentum.
