Nonley Light Up Ice Cubes for Drinks,96 PCS White LED Ice Cubes Liquid Activated, Glow in The Dark Waterproof Ice Cubes for Home Bar Supplies Summer Party Wedding Decor

They work just by adding liquid. Excellent product.

We planned an Outta this World celebration and wanted signature cocktails that glow. These were PERFECT! They completely set the drinks apart. One really cool thing about them is that they don't start glowing until they are submerged in liquid! So we didn't have to worry about them running out of power or dimming too soon.

Purchased these in red and blue for my husband's Star Wars themed birthday party. They were definitely a hit!!

The 96 light up cubes are packaged in 8 separate boxes of 12 cubes in a box. Everything arrived in good shape. I only opened up one box, and each of the individual cubes lit up once they went in the glass of water. Each one would settle into the water right side up no matter how they went in. Then I put 6 of them into one small glass with water, how festive the glass was. I ordered the reds ones. It was so much fun watching them. They didn't actually do anything, but with the kitchen lights off ,the cubes just set off a lovely glow. I took some pictures, but none of them showed what my eyes actually saw. The photos on the Amazon product description are more accurate. When I took the cubes out of the water and laid them on a towel, each one turned itself off. It truly is water activated. The package says "Lights up for 12 hours" and the product description said the battery will last from 12-30 hours. Elsewhere in the description this statement was made "The light time is about 20 hours, and the ice can keep brighter in 4-8 hours, after that, it will be less and less light." I don't know which statement is accurate. All I can say is they should last through a party or event, but after that, the cube will probably light up again (after being cleaned) for some amount of time. But eventually, the battery inside the cube will fizzle out, and it won't light up anymore since the battery cannot be recharged or replaced. So enjoy them while your gathering is happening because all bets are off after that. But who knows, you might get an extra evening or two out of each cube before they are done providing any entertainment.

These are ridiculously fun! Summer nights on the patio just got a ton more festive!You don’t freeze them, so they need to be used with real ice to cool a drink. The come on automatically when wet, and according to the box last about 12 hours. So you can reuse them as many times as you can in that amount of time. They float in beverages so they mix nicely with real ice.I got a set of 96 so they should last a good long time, but I do think the price (at the time of review $69.99) is way too much even for 96 LED cubes.I got white, but in the pic they look blue because the plastic glass for patio drinking has a slight bluish/purplish tint, and the wall behind even though it is dark for the photo is aqua throwing off the color of the light.
