12oz Color Changing Stadium Cup, Durable plastic cups, BPA FREE, Reacting to ice cold liquids, Set of 12, Pink to Purple - MADE IN USA

Used these in place of a goodie bag at my kid’s bday pool party. Put the goodies tied in a cellophane bag inside the cup then had the kids use the cup later for homemade snow cones. Wish I had taken pictures! Only picture I have of the cups the hot mess aftermath of making the snow cones in the background of a picture. You can see the cups really change from yellow to green very well! We’ve hand washed them a million times from August to December and they still work as well as they did brand new.

I have at least 4 sets of different colors…I am a K teacher and every year my kids are SO surprised the first time the cups change color at lunch. Has to be ice cold from the refrigerator milk (liquid) I know some people say they don’t work. Tap cold water doesn’t work as well. I just got the red frosted and got vinyl holiday stickers to make my own holiday cups for my students. I’m excited to see their reaction on Monday,

Kids like them. May consider a bigger size

I bought these and put names of all my child's classmates on them for Christmas and filled them with candy. The color change was great! It is our school colors so it was perfect.

Didn’t come with lids.

The quality is good, but I received only blue and red, not 4 colors, as displayed. The green and purple were substituted. I'm not happy with that.

These are not 12 oz cups, they are smaller, 10 oz.

Brought some of these home from a work convention a few years back and the kids love them. We brought home about 8 of these cups and they were all of the blue variety. After two years, they kind of lost their color and started to yellow. When we finally threw them away, the kids were pretty disappointed. We ordered these from Amazon and the kids are enthralled again.They were very excited and pleased to see that these cups were a mix of different "magic" colors. They can tell by looking at some of the cups which color they will end up, but not all of them. There are some cups that surprise them every time. Its a cute idea and it makes drinking Ice Water fun again.The glasses themselves are very sturdy and I doubt they will ever break. I think that our original ones were left outside in the hot sun and thats what caused them to get yellow and nasty. We'll try to prevent these news ones from being left outside for an extended period of time.

Super cute and my son loves them. Honestly they were not what I thought they would be but they hold liquid and change color and my 2 year old thinks they are the best thing since paw patrol sooo they were a win.

Changes colours and good size.
