Q: These wraps were not doing anything when we placed them in "hot" water. We searched the internet and found others having the same problem. The instructions are very poor. First off, you need to dip in boiling water (or at least some temperature level above what I would call hot). Second, the instructions don't describe what should happen, should the image shrink around the egg, transfer to it -- what?Needless to say, it was frustrating for a minute or two, but my wife - who is very intelligent and great in the kitchen - immediately thought, "well... hot water wouldn't do much to change the properties of the plastic, so let's try boiling water - nothing to lose."Should be more explicit in the instructions. (We were using the star wars version of this product).
A:
Negative
