Hot days are already inching their way back here in California….I found this project in one of my favorite science book for kids: Science Arts: Discovering Science Through Art Experiences. It’s a great combination of science and art projects all wrapped up into one.
For this project I started out by buying two 25 pound blocks of ice from a local ice company, North Hollywood Ice. No pun intended but that is a very cool place, I mean that’s what they sell all day, ice. Places like that don’t exist everywhere….
The idea behind this project is to make sculptures with the ice using a combination of warm salt water and plain old salt. Here’s how it goes:
- Spray bottles
- Warm water
- Colored Salt
- Food coloring
- Ice blocks (buy them or make your own by freezing water in old milk cartons)
- Salt shakers
- Place the blocks of ice in a water table or large tray outside.
- Fill the spray bottles with warm water then add a few heaping tablespoons of salt to the bottle, drop in some food coloring, cap it and shake to dissolve the salt and mix the color.
- Fill your salt shakers with colored salt.
- Hand your child a spray bottle and/or salt shaker and tell them to spray and shake to their heart’s content.
- The salt will begin to melt the ice and stipple the surface. If you spray the salt water at the same spot over and over again you can make holes in the ice.
- The salt will also crystallize to form a crust which you can peel off.
- At one point I ran out of salt and gave the kids the food coloring bottles. They dripped food coloring directly on the ice and it looked pretty cool. Very vivid colors that melted into streams.
Just make sure no one sprays each other with the salt water, it can sting the eyes!
