Make these special ice blocks, and your child can use them to build a wall or a castle
- Tempera paint
- Cardboard milk cartons
- Mix tempera paint with water, pour into cardboard milk cartons, and freeze to make large, colorful ice blocks.
- You can freeze them outside if the weather is cold enough, or use your freezer if you have room. (If you like, make smaller blocks by freezing colored water in clean plastic food containers or ice cube trays.)
- Show your child how to build a wall by sticking the blocks together with water.
- The wall will last a long time if placed outside, out of direct sunlight, and temperatures remain below freezing.
