Freezing small objects in bowls of water and then excavating them is one of our favorite summertime activities (this is the 3rd year that we've done this)!
O and her cousin had a great time using spoons, salt, water, etc. to remove the objects from the ice. O eventually took her block of ice to the carport and threw it down as hard as she could. She had to throw it a couple of times, but it eventually shattered and sent pieces of ice and objects flying. She was very excited! The girls gathered the pieces of ice and put them back in the freezer...they plan to make ice sculptures with them one day :)
