The Levitating Moon™ Lamp – 3D Printed Model – مصباح القمر

The moon lamp is able to float through the magnetic connection created between the lamp and the base. As long as the Moon Lamp is suspended in the magnetic connection, the lamp will be
lit. The lack of friction means that one spin can last for hours. If you prefer
the lamp to be still then simply put your hand on the moon for a moment to keep
it still.

This means you can have the lamp on while studying for your astrophysics exam,
mapping out a new design or simply to show others the marvel of modern based
living.
