I definitely recommend doing this outside because it's quite messy. To prep, mix 2-3 drops food coloring and water and pour into an ice cube tray. I used a flower shape silicone tray I had but any ice cube tray will work.
Once your cubes are frozen, pop them out and your ready to paint! G loved these and we invited a neighborhood friend to paint too.
Keep an eye on your tot during this activity because the cubes could be a choking hazard. After G painted a few pictures, she really enjoyed holding the cubes and feeling them melt. Overall, this was a total hit & I think I'll keep a few colored cubes handy for another day!
