So on Tuesday while we were both off I set him up with a science experiment that went over like gangbusters and I got to enjoy this:
(I lead an exciting life I know)
jelly roll pan or 11"x13" pan filled with baking soda
4 or more cups or mugs filled with white vinegar and different food colorings
1 medicine dropper
Tell your kid to suck up some of the colored vinegar with the medicine dropper and squirt it in the baking soda. Watch him paint for hours!
This is a great rainy/snowy day activity. You can teach science, color combinations, and fine motor skills all at the same time... and you can drink your coffee while it is still hot.
