Giant, Frozen Marbles!

I live in West Michigan. Today it is in the upper 50's - when I was a child the ground was covered with snow by now, but not the case for the past few years for sure.

But, it is Michigan. At some point it will be cold and the ground will be covered with snow. When this happens, we will be able to try this fun, cold project . . . Giant, Frozen Marbles!!! All we have to do is, fill balloons with water and add food coloring, set in our yard, and then once they are frozen cut the balloons off, place around the yard and they will look like giant marbles! 

What do you think? I can picture these "giant, frozen marbles" scattered around my yard! Maybe we will add a small toy so when we place the giant, frozen marbles, we can then keep an eye on them so when they melt the boys can go on a treasure hunt to find the items which were frozen inside! Hmmm . . . sounds like a great activity for days of fun in the Spring! Enjoy!
