Merkury Innovations Jellyfish Lamp Motion & Multicolor Leds – Easy Mode Switching, USB Powered – 9″

I do not recommend this. I do not recommend this at all. My kid was so excited when I showed her that she wanted to put it together quickly however, when we went to fill it up with water, water started coming out of the port we are suppose to plug it into.
We were both sad because of this but I am glad I caught it before we decided to plug it in. It was not a slow leak either, it was gushing out. So I would highly recommend you stay away from these because they are not good at all and could be a fire hazard.
Also the motors in them do not last long and other have slow leak so save yourself the trouble and get something else.
I recommend the JSOT ones because they you can use the charger or get batteries for it so you do not have to worry about the water pouring out the power port like the Merkury did.
