If your child loves outer space, this game is sure to be a smashing success.

Travis and I talked about how comets are made of ice and dust, and decided to make our own. I froze ice cubes and then crushed the ice in the blender for a more easily workable texture – the crushed ice was a big hit!

Then we sprinkled on sand, making a sandy dusty comet-y mix. Travis loved watching the two combine.

Once we had a good mix, I packed some into a plastic cup, and we added a little bit of extra water.

Place your comets in the freezer until solid.

Now comes the real fun part – take the comet outside and toss it on the ground so you can demonstrate what happens when one collides with a planet!
