The entire cost was under four dollars - the bottles of generic pop were 78 cents and the roll of Mentos were 99 cents. The food color came from my kitchen - presto - patriotic fountains which were safe for the kids to play with. ( I have to admit that I also turned it into a science lesson, but don't tell the kids because they still believe they are on summer break! ;) )
For more ideas on inexpensive fun for the 4th of July, check out the episode of Talk of the Nation's Science Friday which gave me the idea - available at: http://www.npr.org/templates/story/story.php?storyId=106246274 .
Hope you had a great 4th of July! Until another frugal moment hits -
