Make colored sand art by stirring a chalk stick in a bowl of salt. it changes the color. Stir less for light color and more for dark richer color. (I used to do this with salt and food coloring. but the chalk stick idea is brilliant!
Neat idea for a kid's birthday party, tie balloons to favor bags. They will be festive party decor, plus every kid wants to take home a balloon! maybe that way I don't forget to give the favors tobtge kids!
