Description：Anti gravity fountain lamp utilize principles of basic science to create an anti-gravity optical illusion that water drops will go up.The item is made of aluminum that forms an elegant shape.When placed in the dim environment, the water does not actually levitate. It just looks like it's levitating because of the frequency of the light's flashing.It's an optical illusion.The product is suitable for use in scenes 3 meters away, which is quiet.Product ParameterPower: 3 WAdapter input: 110-240 VOutput: 12 VDCSize: 6.2 x 6.2 x 10.6 inchWarm PromptAbout the shining of the lights：The working principle of Anti-Gravity Air Purifier requires the lamp bead to be maintained at the frequency of 50.28hz to present the effect, about 7.3% of users will feel the light shining, generally placed in the room for a day or two can adapt, and no harm to the eyes.About the Sound：Because the machine has a water pump running, there must be a little noise (within 35 decibels). quieter than most air purifiers and air conditions. Some users feel louder because they are too close to the product. The product is suitable for use in scenes 3 meters away, which is quiet.About the first boot cannot absorb water：The pump exhaust is not complete will cause unable to absorb water, the proposed solution is as follows:1/ Air bubbles will be expelled from the shaking machine when the machine is on.2/ Pour out the water after interruption of power supply. The machine stands upside down to empty the water in the water pipe. ADD water again before starting the machine.Notes:Due to the light and screen setting difference, the item's color may be slightly different from the pictures.Please allow slight dimension difference due to different manual measurement.
