Tube kit for Magnetic Propagation Replacement

Select your amount of tubes and magnets. All orders come with 1 vial of glass glue Instructions: Determine which side of the magnet pairs with your base. Place a drop of glue on the opposite side of the magnet, carefully apply it to the etched spot on the glass, and lay the tube horizontally on a safe, flat surface, where it won’t/can’t roll. Allow the glue to cure for at least 1 hour. If you mess up with the glue, it can easily be cleaned off the glass with windex before it has cured, so keep a bottle of windex and paper towel handy, just in case you need it.
