You can read Lego Science: An Ice Excavation Experiment. for an amazingly detailed explanation of a science experiment using Lego mini-figures. What I shared below was just a partial execution named Santa Rescue Mission.
I did the activity with my son two years ago and he really enjoyed it.
The day before this Santa Rescue Mission we had frozen him 🙂

I asked my son, ‘Santa gets lost in the ice. How can we save him?‘ Then we had some discussion of possible ideas. Of course, he would prefer the wreck-it approach.
- One, we can use a tool (e.g. spoon) to extract him, but it may harm him.
- Two, we may use salt. Let’s see what happens 🙂
