At start all of the Moondrops come with the magnets inside. You can turn any of them into Earth version by simply changing the magnet direction.
To do that unscrew the top of the Moondrop ''Earth'', remove the magnets from inside (they will pop out so be very careful) and then connect all 5 magnets together with their natural polarities. They should naturally connect with each other when placed together. Then just put them back inside. This way you will get the same mass as other Moondrops and the ''Earth drop'' with no resistance. If you ever decide to create the slow fall again just follow the ‘’How to put back magnets properly’’ section.
NOTE!!! Please be careful with the magnets as they are very strong and fragile so they can chip off when hit each other. We recommend to do everything slowly.
