Why not do this on sand? Snowy day activity: Fill bottles with food coloring and water; go outside and paint. I did this with the kids but with spray bottles. The squeeze bottles would be much better. Going to use those next time. So much fun!
Wow. Fill a round balloon with water and set outside until almost frozen through. Run hot water over frozen globe until balloon pops off. Pour out unfrozen water from inside and insert a tealite. Makes a great walkway accent. These are gorgeous.
