Query: Great Concept but falls short there.

I thought this would be the best gift for a little girl that LOVES the Beach. However this is not something that I love. It comes with very little sand and does not seem to puff up like it says it should once you open a package of it. The colors that you can purchase only mix together and become a colorful blob (yes basic common sense would know this). In addition it is very difficult to get the sand out of the molds once you mold it (impossible for a 4 year old). Probably due to the fact that you need to pack the sand in so hard to make it mold that it is very difficult to get out even after washing the molds in warm soapy water as suggested in the directions. Like I said in the tital great concept but falls short of being good. Stick with real sand.
