Quite simply, we use LED lights, water and a motor that allows the silicone jellyfish to look almost life-like with their movements. The lamp's outer shell is Acrylic and not glass, so it will not shatter if dropped. The LED colors can be set to multi-color changing mode.
The lamp is not completely sealed, there is a small hole with a cap on top that allows you to fill or drain water at any time. You may use distilled (best clarity) or Tap water! This really is a steal at $49.99 USD For Medium and $79.99 For Large. On sale for a limited time until Mother's Day!
