Instructions
Preparation
Fill molds by pouring tap water or colored water into them. If you’re using colored water, add a few drops of food coloring.
Drop small toys or treasures into the water-filled molds.
Place the molds in the freezer for several hours or overnight until completely frozen.
Set Up the Excavation Station
Once frozen, run warm water over the outside of the molds for a few seconds to help release the ice.
Place the ice blocks in a shallow tray to catch any melting water.
Start Excavating
Distribute excavation tools to participants, using spoons, brushes, and mini shovels.
Encourage participants to gently chip away at the ice to reveal the hidden treasures inside.
Experience the Melting
To speed up the melting process, sprinkle salt or sugar on the ice.
Discuss what happens when ice melts and how temperature changes affect it.
Notes
You can change the color themes or toys according to different seasons. Use smaller molds for individual projects, or larger molds for group activities. For an aromatic experience, consider using flavored water for ice.
