Liquid Activated Multicolor LED Old Fashioned Glass ~ Fun Light Up Drinking Tumbler - 10 oz.

Will surprise your guests when these glasses light up immediately when liquid is added .

Very cool glass...

Glasses are cool. When liquid hits, it lights up. Bet the material is a very cheap plastic, scratches very easy. Hand wash and dry to keep a nice look longer. Might last 1 month with slight use.

You don’t have to do anything with battery, works instantly. It startled me how quickly it worked and how great it was!

Great way to liven up the party and a great conversation piece. I would use them more often if they would stay lit on one color.

Still working after several months. Makes your drink easy to find at parties. Always get a lot of comments about it.

I bought this as a fun glass for my Mom and she really got a kick out of it

She like fun full color cool cup u cup turn on battery the. Pour water in cup later see color
