Fill the balloons with water.

Ta-dahhhh! Giant ice marbles!
Take it further
Place the ice marbles around your garden or outdoor space for decoration.
Try playing marbles with them.
Consider these questions:
How long does it take for different-sized spheres to freeze?
What happens as they start to melt?
Make ice marbles in the summer, in your freezer, and play lawn bowls with them.
