Place plastic toys in each muffin cups in a random way.
Then fill muffin cups with water but leave a little room on top, so the ice can expand.
Stick in freezer and let it freeze for about two hours.
Once completely frozen, pull out of freezer. Grab a hammer & safety goggles if you have them.
Have your child help you remove the ice cubes from the silicon muffin cups.
Place them in a pile on the ground.
Now are you ready for a Smashin' good time? Just hammer & smash away until the ice is completely broken. Even throw them on the concrete to break them apart. Then have your child identify each thing that comes out of the ice cubes. Point out colors, shapes & turn it into a game.
