Very pleased! =) - Monday, January 28, 2008They loved it! Reviewed By: Emily Goodey I drew a smiley face on a paper towel, then let it dry. Then, when you spray it with windex (a base) it turns bright pink, suddenly and dramatically. This was part of our acids/bases lesson. The kids loved it! This is a substance that requires adult control and supervision. |
