Flashing Water-sensitive Ice Cube

Product Detailed Description

A glass of punch turns into a moving point of color the moment one of these sealed cubes meets liquid. A pair of contacts waits for moisture to bridge the gap, then the circuit fires and pulses the LED through the clear shell, so a champagne toast or signature cocktail gains a shifting glow.

Build and finish

Each cube is molded from clear plastic with a battery and diode sealed inside, floating at the surface and resealing after every dip for repeat use across a long evening. Thicker walls resist cracking when cubes knock together in a bucket, and a snug battery compartment keeps moisture away from the cell. Buyers should confirm seal quality, since a weak closure invites leaks that end a cube's life early.

Gifting fit

Promotional suppliers and distributors stock these for bars, weddings, hotel programs and beverage brands that want a giveaway guests keep. Request samples to check brightness, switch response and color consistency across a run, and ask how the cube behaves in carbonated or sugary drinks before committing to a large order.
