I was glad I found this because my daughter wanted to test what happened between using cold and hot water. First, we tried hot and cold water and there was not much of a difference and then I found this and it really worked. The best results were right after they froze, the longer they were frozen the less clear they became. This would be great for putting something inside of for a party. Just be sure to use them as soon after they have frozen as you can, that way they are much more clear.
